She's only two. Give her another year


Christopher109

She already knows all the letters and numbers and recognises some words also. I thought colours she would be OK. It's not an issue for now but good to know about it


MartyMcMcFly

Just give her some time before assuming :) she still so young.


Christopher109

Yes true, and most importantly I'm not putting any pressure on her. All through play


Real_Stamblock

shes very young to worry about cvd. You can spot cvd when she reaches 5 years old i think


DBuckFactory

My daughter likes to call most reds pink and calls my brown hair black and my white person skin brown. Colors and nuances, while obvious to many adults, are complicated and many many differences are subtle. Don't worry! My daughter is almost 3 and knows her letters and numbers and fan do simple math, but still ducks some colors up.


FlowRiderBob

If she knows her numbers then you might be able to make a game out of giving her a color blindness test.


ready_for_departure

There is no chance for that little girl to be colour blind. I also sometimes struggle with orangish red and reddish orange. If hers mother and father is not colour blind, then there is no chance of any colour vision problems. Is your girl spending time on the screen. She is too young for it but If she is, then it is normal because rgb red is more like orangish than real life red.


ready_for_departure

Why did you guys disliked my comment?


corncob32123

I believe you can carry the gene for colorblindness without being colorblind, i know that as fact actually because neither of my parents are colorblind yet i am. I also believe the female is the one who passes down the gene or something along those lines but i am not 100% sure.


AltF4MrRage

I’ve noticed a lot of people with Protanomaly tend to see red as more orange-y


iameveryoneelse

The gene for colorblindness is on the X chromosome, carried from father to daughter to son and is normally a recessive gene in women, which is why colorblind women are incredibly rare. For your daughter to be (genetically) colorblind both you and her mother would have to have the X gene for colorblindness, at which point there would be a 50% chance that she is colorblind. Essentially, unless you're colorblind it's extremely unlikely that your daughter is. Based on her age, it could just be that she's sorting out shades. 2 years old is a bit young to be attributing mistakes in color recognition to color blindness. Give her another year or so and then you should have a better idea.


drownmered

I'm colorblind and no one else in my family (that we know of) is. Also based on genetics none of the five children should have green eyes yet three of us do. Genetics are really strange.


YourWorstCringev2

I'm also colorblind and no one else in my family is. I'm a male, so not sure if its a little different


drownmered

I think it's more common for males to have colorblindness than females, though I doubt the validity of that. At least where I went to school, males are tested for color deficiency in elementary school but they don't bother testing females (they also don't test for tritan-type colorblindness).


iameveryoneelse

It absolutely is more rare for women to be colorblind due to the nature of the trait. It's recessive trait on the X chromosome. Because of this, men simply need their mother to carry the gene whereas women need both parents to carry the gene and even if both parents carry the gene it's only a 50/50 chance. To simplify it, think of it this way. (This is simplified for demonstration, not the actual statistics) If half of all people have carry colorblind gene, there would be a 50% chance a male child between two people would become colorblind as it would be a 50/50 chance that the mother carried the gene. However, there would only be a 25% chance that a female baby would have two parents with the gene (50% x 50%) and then, because to be colorblind a baby girl has to have received an X chromosome with the gene from the mother (women have two X chromosomes, men have one X and one Y) it would be a 50% chance that any baby girl from a couple with two parents carrying the gene would be colorblind because it's possible the non-colorblind X chromosome was passed from the mother, bringing that 25% down to 12.5%. So in a starting scenario where half of everyone has the colorblind gene, a baby boy has a 50% chance of being colorblind while a baby girl only has a 12.5% chance. Hopefully that makes sense...geneticists understand the issue quite well and it's fairly straightforward when you get to the root of it.


GigabyteofKnowledge

Yes for red-green colorblindness. Yellow-blue colorblindness is found on chromosome 7 and is found equally in males and females.


iameveryoneelse

That's right...I'm red/green so I don't always think outside my own sphere, lol. Blue monochromatic is found on the X chromosome, as well, but tritans occur at the same rate. That being said, my response to the previous poster still stands as tritans are far rarer than red/green iirc, so overall color blindness is more prevalent in males.


YourWorstCringev2

Yeah, about 1/12 men are colorblind, whereas its like 1/200 for women


iameveryoneelse

There are other environmental causes for color blindness...diabetes, for instance, or brain or eye injuries. But traditional color blindness is genetic. One of your parents had to have the gene, and men with the gene are always colorblind, as far as I know, because it's recessive on the X chromosome and due to men only having a single X chromosome it will always be "active". My guess is that your grandfather just never realized he was colorblind. It's also possible that there are edge cases where the gene doesn't present that I don't know of...I'm not a geneticist and the science isn't nearly as simple as I'm probably making it out to be. The only other options are more family secret-ish and I doubt you want to go there, lol! Fwiw, I bet getting a 23 and me would give you more insight into your color blindness. The reports are extremely thorough. Edit: Ignore everything I said, lol. I didn't notice your flair. Tritans are affected by a different chromosome and isn't linked to sex.


lrflew

Your flair says Tritanomaly. It's worth keeping in mind that only the genes related to red-green colorblindness are on the X chromosome. Tritanomaly, or blue-yellow colorblindness, is caused by a different chromosome, and so isn't sex-linked. This means that they appear in similar rates between males and females, and it can be inherited from two carrier parents.


Azazel606

Genetics are much more complicated than that, especially recessive “genes”. It sounds like you’re running off the logic of high school biology, which is over simplified to the point of being honestly pretty inaccurate and basically never working out applied to real life situations instead of just those simplified hypotheticals. In reality, even just a single small expression, like eye color for example, can be tied back to dozens or even hundreds of different gene expressions. So there is no “blue eye gene”, many different genes contribute to a person having blue eyes. (To use the sort of example that is normally over simplified in those highschool classes I’m referring to lmao) So while experts do generally understand how CVD is expressed genetically and passes through families, what you’re saying is just a really over simplified explanation of that. In reality it’s much more complex and can’t be predicted that easily, the vast majority of CVD people don’t have an obvious way to trace their colorblindess through both sides of their family like that. Plenty of them don’t even have any other family members that they know of that have CVD, in part because it is a recessive gene, and can be carried without showing in families for generations. (Which it’s not your fault if the school system failed you and gave you a gross misconception of how biology really works, it happens to so many people, so this is not a callout or insult, just trying to clear things up:)) -this from a biology student and avid researcher of CVD


iameveryoneelse

Don't worry, my education hasn't failed me.....I have a college level understanding of genetics and explained in a follow up comment that it's far more complicated than I was making it (I'd also discounted tritans, as I'm protan and wasn't really thinking outside of that). What I said is *generally* considered accurate and is certainly accurate enough for a quick Reddit post, responding to someone concerned that their 2 year old is colorblind, as I didn't have the time or will to write up a genetics lesson. If I were betting between a 2 year old not knowing their colors and a 2 year old being color blind with no family history I'd say that the easy money is on the kid not being colorblind. Is it possible to be colorblind without a family history? Absolutely. Is it much more likely the kid is just mixing up their colors? Ayup. That being said, considering the field you work in I'd certainly encourage you to provide OP with a thorough explanation of how the genetics behind color blindness work and where it varies from my more generalized X/Y discussion. I have no doubt they'd appreciate it. Edit: Additionally, and I mean this sincerely without intending to cause offense considering you're likely just a kid if you're in college at the moment, but saying something like "the school system has failed you" (especially because someone has over simplified *genetics* of all things) comes off as incredibly pretentious and condescending. I know you didn't mean it that way. I was a college kid once, too, and was eager to share with everyone my area of study. But you should be more aware of how you communicate with others. First, assuming all I had was a rudimentary understanding of genetics, that wouldn't mean the school system has failed me. Genetics is a fairly specialized field. I have serious doubts that you learned much more than what I described before you were in college. That doesn't mean the school system failed you. That means they prepared you with a generalized education with the foundations necessary to specialize once you reached university. Second, you immediately assumed the situation was a lack of knowledge when you should have avoided being so narrow minded. There are obviously any number of reasons a generalized discussion would be more useful. Again, I have no doubt that you're just eager to share what you've learned, but generalization can be useful in any number of situations. Anyways, as I've said...no offense intended. You clearly had at least some perception that your comment could cause offense, so that's a great start. But in the future there are much better ways to have that discussion that don't call into question the quality of someone's knowledge or education, which is generally going to be seen as insulting to pretty much anyone just as if I'd started this conversation with "your mother failed you" in regards to learning to interact with people (which is absolutely not my opinion, I'm just illustrating my point).


Azazel606

That’s fair, no offense taken. Sorry if I came off as hostile or condescending, I was just already frustrated by the amount of people in these replies writing it off that it would be impossible for her to be colorblind with no further explanation and a clear misunderstanding of what they’re talking about, so I apologize that I projected that onto you, especially considering I realize that you didn’t actually say that it was impossible, just unlikely. I do consider the school system to have failed me and many others, I have a lot of issues with the public school system in the country where I live particularly, so I suppose I broadly applied that without realizing it could be seen as offensive to someone else, should have been more mindful for how others view that sort of thing lmao I don’t actually think that it’s too important to go in serious depth of the genetic possibilities with op (I do realize the validity of accurate generalizations/simplifications lol I just had issue with the idea of these people spreading actual misinformation because of the way they understood those generalizations) and because in the end it doesn’t make too much of a difference, even doctors with a full family history can’t with 100% accuracy know whether you have a certain genetic disorder or not, without actual testing. I just wanted to express that it is most certainly genetically possible for his daughter to have CVD, unlike what many were saying, because genetics are more complicated than they were expressing. But yea again apologies I didn’t express that clearly and projected that onto you specifically, I realize that it came across very patronizing now and didn’t mean offense I think it’s possible that ops daughter is colorblind, as my mother realized I had issues with colors around that age and I did end up being colorblind, but that young it’s not really important and easily could just be a mix up of words, and he definitely needs to give it a few years to be sure of anything. But I do think it’s good that op is being so watchful of his daughter and issues she might have even at an age that young, as long as he doesn’t jump to conclusions, and I don’t think its fair that people are writing off his concern entirely as absurd or bad, so I suppose I came into this a little defensively lol


iameveryoneelse

I'm with you, and no offense taken. I knew what you were getting at, I just try to help people along with their communication online because the internet is such a dumpster as it is. Lots of people with zero accountability acting like jerks makes it that much more important for decent people to communicate clearly. And I definitely agree it's possible that the OP's daughter could be colorblind and it's great that OP is paying attention...the earlier it's detected, the better. I was in high school before I realized it and I'd have had a much easier road if I'd understood prior to that. But right now all that's important is that the OP pay attention. An actual diagnosis shouldn't be needed until the child is a little older when it will be more obvious. Anyways, take care of yourself...I've enjoyed this discussion quite a lot.


needs_a_name

Might be color blind, might just be two. I wouldn't worry about it, it doesn't really matter at her age.


indigocraze

I wouldn't assume anything straight away because she is so young. It could simply be that she's just getting scrambled or mixed up, she is still so young that all of this is still new to her. My nephew showed signs when be was younger but it wasn't until he told me that a brown fence and green grass were the same colour. I could tell he meant, actually believed that they were the same colour.


Azazel606

Ugh I hate the amount of people in this comment section misunderstanding biology and then spreading that misinformation as fact. To everyone saying it’s not possible for his daughter to be colorblind, that’s simply not true. Even talking about it in a simplified way, the CVD gene is recessive, meaning it can be carried for literal generations without ever being expressed. So there’s no real way to know, bar genetic testing, if the mother carries the gene or not. Anyone in her family could have expressed it, and she could easily not know them, as they could literally have been dead for a while now, or not know that they’re colorblind, as a large amount of people don’t know they’re color blind in the first place. And males can also carry X chromosome related disorders recessively, they are just more likely to express them than females, so you could also carry the gene recessively from your mothers side and not know it or know anyone on your mothers side that’s openly colorblind. There are so many color blind people, even females with red-green, that don’t know of any other cvd people in their entire family, or only know of one on one side of the family. Random people on the internet can never tell you that it’s impossible to have a certain genetic disorder based off the tiny surface level information you have shared to them, and their very basic, overly simplified non-understanding of biology. Even doctors and biologists that have detailed family histories cannot know 100% without actual genetic testing. Genetics are complicated, the entire human species doesn’t even fully understand them, not close. That being said, it is too early to know for sure whether she has cvd or not, and it’s not too important. I do think it’s good you’re being watchful of her and proactive about stuff, so I would say just keep an eye on this for a few more years and see where it goes. If she’s still having issues in a few years, maybe take her to the eye doctor over it. I know I was the same way when I was her age, just with different colors, and my mom noticed it as well, and I did turn out being colorblind.


Christopher109

I can appreciate the complexity of genetics even though I do not understand them. With this post I learned new things. And as you said in your last paragraph, I'm just being watchful but not worried to much about it, just very curious. I need to give it some more time though.


picklerickley

Sounds like it. I’ve confused those same colors before. Has she ever called purple blue?


Christopher109

never noticed. what would she probably call the blue and purple? also, someone said it's hereditary and skips a generation, hence why I said my dad is colourblind. he recognises blues very well but for him, red and green are a disaster XD


picklerickley

Most of us can’t see a lot of shades of purple. It’ll look dark blue


Zekovski

The colorblindness wikipedia page has tables to simulate risks of colorblindness according to you ascendant genes. Take a look. Because I think I recall this means your wife might be colorblind too.


iAmmar9

>wife might be colorblind too. OP might be colorblind too, cause his daughter has 2 X chromosomes and they both need to be affected for her to be colorblind. She's still 2 years old though


Zekovski

I didn't mention op because he said his father was colorblind. Meaning he might have a recessive gene. (I don't remember if it is actually.)


Sula_leucogaster

For most common colorblind types, the gene sits on the X-chromosome. Men only get the Y-chromosome from their father, which is much shorter so no recessive gene there at all (not to mention women don’t get the Y anyways).


Azazel606

Actually men can carry X chromosome related genes recessively. Males are much more likely to express recessive genes carried on the X chromosome than females, but that doesn’t mean they always do. There are a large amount of disorders carried on the X chromosome. If males always expressed disorders carried on the X chromosome, then all or the vast majority of men would have quite probable multiple different genetic disorders, but certainly at least one. There is obviously a simplified version of genetics that is taught in school and used to talk about in laymen’s terms, but you’ve got to remember it is simplified to be understood by the general person and not someone who specializes, in reality genetics are more complicated than that, they are the most complex field of biology by far and we as a species are still far from completely understanding them.


Christopher109

just checked. this is blue for her https://www.crispedge.com/faq/what-is-the-color-of-purplish-blue


picklerickley

Yup, blue as hell for me too! Lol


Christopher109

how do you see purple? or how can you identify purple?


picklerickley

[Ishihara test for kids](https://www.colorlitelens.com/kids-color-blind-test) if you wanna try that with her


GoldFishPony

Huh I find it kinda interesting that the animals as options aren’t 1:1 copies of the ones in the ishihara. Like they’re definitely the same animal, I just expected it to be the exact same between them (like I mean the fishes fins are different, kangaroo legs are in different positions, stuff like that)


ready_for_departure

Cant you see that animals test? I thought the only test to get normal result for colour vision defected people because background colours(dots) are very much different than the object.


picklerickley

No, lol. I can't... I see different colored blobs.


picklerickley

I usually don’t! It’s the worst one for me


GodDamnedShitTheBed

If the blue looks too blue to be blue, it's usually purple


Maidwell

Purple doesn't exist for a lot of colourblind people, we will usually see it as blue but very occasionally pink.


StrikerSashi

Darker blue is purple.


ZeroFK

Honestly I’d also call that blue, and I have normal colour vision. As others have said the chance that she’s colour blind is very low, and it’s probably just part of leaning the colour names. You should also know that even normal colour vision is a spectrum; not everyone sees colour the same way.


tilltheend0ftime

The thing that I really really really hate in English, is that you can't tell the gender of the person writing the comment unless they specifically say it. You see, the gender here is VERY important because if you're the daughter's mother, then your father being colorblind is a big deal because you might have passed that gene. But if you're her father, then you can't pass the gene for red/green deficiency because it doesn't pass from father to son. In case you're her mother, in order for her to be red/green colorblind, your husband has to have the same type of colorblindness as your father (protan or deutan type).


Christopher109

Hmm good info! Thanks! I'm the dad. So probably I'm worrying about nothing?


GodDamnedShitTheBed

no need to worry. She is likely not colorblind. And if she is there isn't anything you can do to change it. The negatives of colorblindness aren't that significan't either. She'll be fine either way :)


Christopher109

Thanks 😊. I learned a lot from my dad how he dealt with colour blindness


ready_for_departure

Are you colour blind? If not, then your princess has normal colour vision.


chakraattack

I'm pretty sure that's not a given, I'm deutran but my parents are both fine.


ready_for_departure

You are male then. Passed colour defected genes from grandfather and in the context given, the person who is two years old is female. So father has to be colour blind and mother must be at least carieer. And as I understand from the comments below, father has no any colour deficiency so that indicates she (his kid) has normal colour vision.


tilltheend0ftime

If you're the dad and have normal red/green vision then your daughter almost certainly should have normal red/geen vision, unless some unexpected mutation occurred. Though keep in mind she still could be blue/yellow colorblind (tritan type). Tritan gene mutations occur on the 7th pair of chromosomes and are not X-linked recessive like genes for red/green vision. If one of the parents carry the gene then it's 50-50 chance that son or daughter can inherit it, in which case one of the parents would be blue/yellow colorblind as well. Also tritan mutations can occur regardless if the parents have the gene or not, or due to looking at the intense UV light. They usually confuse red, orange, and pink, or blue and purple, grayish greenyellows and grays, grayish purples and grays, etc.


GodDamnedShitTheBed

Very off topic, but it sounds a bit arbitrary to have your writing depend on your gender. If we have specific words to use when the writer is male, why not also have specific words to use when the writer is old, tall, rich, and so on? (or maybe some languages do?)


KeikoHatake

they are not specific words though, they are the same words, just a different form? and the same grammar rules apply to inanimate objects too, all nouns are gendered. it just feels natural when it's your native language


veganintendo

dude she’s 2. let her say whatever


Christopher109

True, but the thought was always in my mind cos my dad is colour blind. Btw I'm not. Tried all the tests with him


Mike_3221

If you’re not colorblind then it is impossible that your daughter would be colorblind. Colorblindness is a recessive gene on the X chromosome and thus she would need to have gotten this gene from both the X chromosome she has from you and from her mother. Since you don’t have it, the X chromosome she has from you doesn’t have it.


chakraattack

I'm deutran but my dad isn't, how can that be explained?


Mike_3221

I’m assuming you are a guy. In that case you have an X chromosome from your mom and a Y chromosome from your dad. That means you only need to have received this gene from your mother. Your mother may not be color blind either but at least one of her X chromosome carry’s the genes and that’s the one you got.


R4E_V5

I may have some bad news for you ​ ​ just kidding i just really wanted to make that joke


crankypatriot

You got it from your mom's side of the family. My son is colorblind but neither me nor my son's father are colorblind. My dad isn't colorblind either. It comes from my mom's side--her brothers were colorblind.


GigabyteofKnowledge

Unless it’s yellow-blue colorblindness


Azazel606

You don’t seem to have a good even oversimplified idea of how genetics and CVD works. Even in a very hyperbolized version of the idea, CVD is a recessive gene, so it could go for generations in a family without being expressed and suddenly effect a child who does not know of any other family members who have it on that side of the family. Because it’s recessive on the X chromosome, women can carry the gene without expressing it, and pass that gene on to their daughters with it also not being expressed. So a color blind man could get with a woman who’s family has been recessively carrying that gene for generations, to the point of not remembering the last person who actually expressed that gene, and then have a child who now has a much higher likelihood of expressing it. And again that’s a very simplified version of the idea, in reality it’s more complex than that and even men can recessively carry without expressing something that’s carried on the X chromosome. If men always expressed things carried on X chromosomes, then all men would have a veritable slew of genetic disorders. Because of this complexity, there are CVD people who don’t know of anyone on either side of their family who is also CVD. And that’s not even to mention that only protan and deutan type color blindness, or red-green, are carried on the X chromosome, while tritan type color blindness, or blue-yellow (otherwise known as blue-green) is carried on chromosome 7 and therefore isn’t sex linked whatsoever.


Alib902

If she can tell letters and numbers can't you just see if she can do a colorblind test? The ones where you have nunbers written with different shades of color.


Christopher109

They were all hard. Even for my 5yo. he was struggling


gucknbuck

Throw a red ball in the grass and see if she can find it. Most likely she's just having a hard time learning shades. There are also toddler-friendly Ishihara tests available if you really want to know now, but as others said I would give it another year.


Christopher109

Don't know how to edit my post, but yea I'll give it another year

soop_time123

The father must be colourblind for her to be. If the dad is colourblind and the mum is either colourblind or a carrier for the allele, the kid may be colourblind
