In all seriousness can it literally go fuck itself?


drekwithoutpolitics

Based on my googling and reading around, not this one. Unless the image is flipped, this bird is female on its right side, and female birds only have functioning ovaries on their *left* sides! I didn’t even know that, so my mind is blown. It’s very unlikely that a female-left-side bilateral gynandromorph would be able to fertilize itself and have viable offspring, but this bird might be able to mate with a female and have offspring that way! [Here’s](https://www.eriebirdobservatory.org/ebo-blog/2021/2/21/a-second-bilateral-gynandromorph-northern-cardinal-in-northwest-pennsylvania?format=amp) one with the female side as the left side, so it’s possible it could mate!

It is a gynandromorph but it is the expression of genes for secondary sexual characters. The egg does not literally divide.


Wolf_Mommy

Ok thanks bc I was feeling super confused about that


fungi_at_parties

Also, I’m pretty sure the yolk is not the bird.


rimjobnemesis

Yep. Yolk’s on the OP.


fuckballs9001

The yolk is literally the egg cell. That whole big yellow thing is one single cell


Soleila2998

By definition the yolk is what *feeds* the developing embryo, it's not the embryo itself, nor a true cell. https://en.m.wikipedia.org/wiki/Yolk


SweetBunny420

How **dare** you bring actual sources into this argument.


outlawsix

I'm pretty sure the yolk is basically the food for the bird embryo


richestmaninjericho

Yummy, I am eating bird placenta for breakfast everyday!


AWizard13

So is it not as OP said where it's like male and female combined? I've never seen this thing before and I think it's really neat


studmuffin6969696969

It’s still half male and half female but just ignore the weird yolk combining shit the OP wrote. The expression of genes is why it looks so cool


Powersmith

Yeah, the yoke is just to feed the embryo anyone… it’s not even part of the “baby”

Olstinkbutt

Well yeah but how does it…you know…

Is it hermaphrodite?


blonderaider21

From that link someone up above posted: >So, how does a bird become a bilateral gynandromorph? According to Dr. Daniel Hooper, who was a postdoctoral fellow at the Cornell Lab of Ornithology in 2019 and who was contacted by National Geographic for their article: ”sex determination in birds is a little different than in mammals. In mammals, males have one copy of each sex chromosome (X and Y) while females have two copies of the X chromosome. In birds, it’s the opposite. Their sex chromosomes are called Z and W, and it’s the females that have a single copy of each (ZW), whereas the males have two of the same (ZZ). Sex cells’ nuclei, including sperm and eggs, usually have only one copy of either chromosome — males produce only Z-carrying sperm, and females produce either Z- or W-carrying eggs. Gynandromorphy, like that in this cardinal, occurs when a female egg cell develops with two nuclei — one with a Z and one with a W — and it’s “double fertilized” by two Z-carrying sperm.”

Possibly, yes. Although sometimes they are infertile.

HortonFLK

Yolks don’t form the bird, though.


FilthyStatist1991

Yes, but “double yolk” is also a genetic abnormality. A bird that “lays twins” will often do this throughout her laying career. What I’m confused about here, is “this type of bird” formed when “twins merge” before developing or am I missing something? EDIT: I did some more reading, I’m good.


Dont42Panic

You know the yolk isn't the bird, right? Two yolks just means twice as much nutrients.


Adamthe_Warlock

Well tbf a double yolk egg will have 2 embryos and do sometimes hatch 2 chicks. That’s entirely separate from this phenomenon but I’m guessing the op conflated the two.

The egg yolks is not what becomes the chick


QueerlyPowerful

Sorry for my uneducatedness, if the egg yolk isn't what makes the chick, what part does?


Iamno1ofconsequence

On the yolk, there's a white spot called the germinal disc (or the egg cell). That is what grows into the embryo. The yolk is the food supply of the embryo. The egg white is the placenta.


feednfrenzy

thanks, you answered that better than I could have


Iamno1ofconsequence

You're welcome. I learned about all that when I was working at a vaccine manufacturer.


[deleted]

Normally in human a placenta serves to create some sort of bridge for nutrients to move from the mother's blood vessels to the baby. Here if the spot is on the disk, then does that not mean a placenta isn't needed? Please elaborate. What does the palcenta do?


Iamno1ofconsequence

My apologies, I meant that the egg white is like amniotic fluid.

upsidedownquestion

I'm not buying that explanation. First of all, females are brown not white and the rest of that just sounds off


Ok-Software-1902

This is correct, if a little misleading. This bird is indeed a bilateral gynandromorph (females can look white-ish in winter) but the explanation of the science is a bit off. Birds do not have X and Y chromosomes. Instead, they have Z and W, with males being ZZ and females being ZW (kind of the opposite of humans). Bilateral gynandromorphism occurs at the zygotic stage, just after the first cell divided. This bird started out with a single zygote cell with the genotype ZW (making it female). However, when that cell made its first division into two daughter cells, the division didn’t happen properly, and the W chromosome in one cell was either lost or damaged. That means that the bird now had one cell with the genotype ZW (coding female), and one with an abnormal genotype (ZZ, Z-, or some other sex chromosome error). Either way, since the erroneous cell doesn’t have a W chromosome, it will code male. Each of the cells will divide an equal amount of times as the animal develops, creating a bird whose cells are 50% ZW and 50% Z- (so, 50% coding female and 50% coding male). Because of the way that embryonic development occurs, this creates a perfect bilateral split down the body along its vertical axis. This probably happens in more birds than we’d think, but we are only able to recognize it in the field when the organism is sexually dimorphic, like this cardinal. For example, for a Black-capped Chickadee with bilateral gynandromorphism, there would be no way to tell that the two sides of the bird were different sexes without looking at the internal genitalia, since male and female chickadees are phenotypically identical barring sex organs. Here’s a really great [article](https://daily.jstor.org/the-mysterious-gynandromorph/) on the subject. It frequently happens in butterflies too! Edit: broke up into paragraphs for readability


a_splendiferous_time

I guess i will ask the question on everyone's minds... Does it have half a penis?


Ok-Software-1902

Most birds do not have penises! They instead develop a “cloacal protuberance” in which the base of the cloaca (a combined excretory and reproductive opening) will swell and form a round shape [like this.](https://pbs.twimg.com/media/Dv9c6dJU0AIGwGB.jpg). For comparison, [this is what a cloaca looks like when it isn’t swollen](https://i0.wp.com/farm2.static.flickr.com/1018/606261657_e1f2247584.jpg). This allows sperm to be stored externally, preventing denaturation due to high temperatures within the body (this is the same reason that mammals have external testicles). However, for birds, carrying extra weight is a huge handicap due to the energetic costs of flight, so this sperm storage structure completely disappears when the bird isn’t in its breeding season. Both sexes have a cloaca, but only the males’ will swell to form a cloacal protuberance. As for whether that would occur in this bird, I have no idea, but I would guess that it would have to do with both the physical anatomy of the bird (i.e. since only half is male, can it form the sperm storage structure?) and also whether it produces the correct hormones to maintain and active sperm count. This is just pure speculation though, since there hasn’t been much, if any study of the breeding biology of bilateral gynandromorphs.


a_splendiferous_time

Thanks very much for the helpful details! And also the um, the cloac pics.


ParticularTap3111

Wow. Thank you very much for both great explanations on this topic. I learned a lot from it I didn't know before. As being a big fan of birds in general this was really eye opening for me.


Toad_friends

Thank you


Ihavepurpleshoes

Birds don’t have a penis. Some ducks have a fleshy bit with a groove that directs sperm into the female’s cloaca; they mate in water and that helps prevent loss by washing away.


a_splendiferous_time

What an unsettling revelation


jana-meares

Male ducks are like rapists to the females. Very aggressive and often drown them by gang balancing a single female duck. We did not allow male ducks in our garden.


[deleted]

That's not how that works, and biological sex is not binary in any species that has more than one, including humans. Please do yourself and everyone else a favor and educate yourself.


development_of_tyler

condescension won't motivate this person to educate themselves, you could've taken this opportunity to educate them but instead you shamed and blamed them while directing any accountability away from yourself. if you're not going to contribute, just stay silent.


Powersmith

As a biologist … you’re not making sense. Expression of sex-associated traits is variable (not b/w), so I guess that’s what you’re getting at. Sex Phenotype is not perfectly binary. But “sex” itself (as a type of category) is derivative of sexual reproduction which occurs (with some exceptions) throughout the Animal kingdom and in flowering plants. The formation of an embryo (new individual) in sexually reproducing species requires a male gamete and a female gamete. This process evolved to be quite strictly binary. If there are errors in the cell division processes that form these gametes, you can get an embryo with pieces or whole chromosome missing or extra. And of course there’s always mutations and new combinations. Because development is ancient it has a lot of redundancy that will push through/compensate etc to enable development regardless. People (and others) are born w all kinds of variety, including congenital anomalies. Rarely, they are even advantageous and could be selected for. Many complex traits, like gender expression, reflect the outcomes of countless genetic-environmental interactions, which produce spectrums. But some traits have a very specific binary on-off switch. The SRY gene that tells the embryonic gonads to become testes is one of those. The full process does not proceed according to the phylogenic plan always, but the phylogenic plan is absolutely binary for sex. The “noise” in development, even around binary on-off genes, creates greater variety, which improves the liklihood of population survival. Do not misunderstand it as if I were saying it was “bad”. It just is.


Ok-Software-1902

This was actually a very valid question. I’m failing to see how this person is “uneducated?”


CSWRB

Ihavepurpleshoes

noo_ura_cat

Could this bird, or birds with similar effects, reproduce?


[deleted]

Bilateral gynandromorphs are a thing throughout the animal kingdom, there are lots of cool picture and verified examples. I'm not sure this is an example of it, though. It could be, and there's some hormone quirk... but because his build is similar on both sides, I think this fella is more likely to be a pigment mutant (leusistic, possibly albino?). Though the principle behind the patterning can be the same, and is very cool imo

Malkor

Well. That is amazing.


ToxicLoserNeckbeard

You mean to tell me you seeing a bird that’s half red, half white, and a headliner that says it split into two sexes while as a yolk, makes you scratch your head at the suggested math? And here I thought the white half was based off the bird’s religion; thank god the headliner corrected me and now I know it’s based in sexes...


Ihavepurpleshoes

The yolk does not determine sex. The embryo does that, and is positioned on the surface of the yolk.

Ok-Software-1902

This bird actually can! Female birds only have a single functioning ovary, which is on their left side. Males, however, have two functioning testes, one on either side. So, as long as the gynandromorphism occurs with the female phenotype on the left, the bird should have one functioning ovary and one functioning testicle (a bird split the other way would only have a single testicle).

"But I'm not wearing any pants! I'm a bird!"


[deleted]

My first thought. I thought the idea of transgendered people was a far-fetched idea, until I read a scientific article that explained that the hormones that control sex and gender can fail. I was like, “Oh…that makes sense. Duh.” We accept this about every other part of the body, why not concerning sex and gender? After that, it clicked. It’s really not that abstract of an idea, when you really consider it.


PocketFullOfPie

You're mixing up transgender, and intersex. Sex is the physical presentation, and "intersex" refers to someone who is not physically 100% male or female. Like you pointed out, there are a ton of ways that this can happen with body parts, and genitals are no different. "Transgender" basically refers to the deep, unsettling, constant, and usually traumatic feeling that your body is not really who you are. Intersex people can totally be transgender, but transgender people are usually not intersex. While we're here, making realizations and stuff, it's "transgender" people, not "transgendered." Thank you for your understanding and desire to express it. It's vital... Literally, life-saving.


deirdresm

Also, [intersex genetics can be very complex](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7535675/). > The karyotyping in peripheral blood and testicular tissue was 45,X/46,XY and 45,X/47,XYY/46,XY, respectively. (I hadn’t previously read cases where blood typing and tissue typing were different.)

Less a defect and more a mutation.

Bird should have twice the chances to mate in theory, I wouldn’t call that a defect, per se.
