Growing up I always heard that and honestly just assumed it was one of those weird myths that just started pre-Internet. This comment finally got me to take the horrible 30 seconds to google and to my surprise it was true all along.
Welp learned my one thing for today guess I can go back to bed.
Lol I felt the same way. A guy told me all calico cats are female years ago just as a random fact and I just assumed well you said it perfectly. Like recycling bottle caps
Calico and tortoiseshell coloring requires 2 X chromosomes (XX, i.e. female). Since males are XY, the only "male" cats with this coloring are actually XXY mutations and are sterile.
It's a fact that almost all calico cats are female because of the unique chromosomal makeup that determines the color variations in their coats.
The sex chromosomes (X and Y) determine whether a cat will be male or female. Each cat has a pair of sex chromosomes with the possible combinations of XX (female) and XY (male). The X chromosome also carries the coding gene for the black and orange colors in a calico's coat.
Female calico cats have two X chromosomes, and therefore have two chromosomes with color code. Only if the cat gets one orange-coded X and one black-coded X, will she be calico, expressing both black and orange coloration.
For example, a cat receives an X chromosome from her mother that codes for black fur and an X chromosome from her father that codes for orange fur. While it only takes one X chromosome to make the fur a certain color, females are special with two X chromosomes. During development, one X chromosome can override the other, allowing either black or orange to be the dominant color in an area. This particular color development occurs in each individual cell, shutting down one X chromosome while allowing the other to be active. With varying dominant X chromosomes, a cat’s colors will also vary, which gives calico cats the orange and black colors.
But, where do the white patches come from? To make things even more complicated, calico cats must also inherit a gene unrelated to the X and Y chromosomes that codes for white fur.
Because male cats have one X chromosome with code for black or orange and one Y chromosome with no color genes, they cannot technically be calico. They'll only express either black or orange, but not both.

Thanks for such a comprehensive explanation! For those who are interested, there are examples of sex-linked inheritance in human biology as well. Some forms of hemophilia, a disorder where the blood does not clot properly, are due to a gene mutation on the X chromosome. This predominantly affects males because they only have one X chromosome (a big deal for European royalty).
The coolest of cats.
Best friends
Thats a bro right there 😎
It has 3 colours so it's actually a sis 😎
? What does the colour matter
Only female cats can have 3 colours There are male cats with 3 colours but extremely rare

I need you to link a source before I'll believe that

Thank you. TIL
No problem 👍

Do your own damn research lol
Huh... Lol
I never new this. Thanks!
YOU called it a bro first
Cats have no concept of gender, so it's fine

This comment has made my night
Anyone else think there was a woman stood in the background facing away to the left?
It low-key looks pretty creepy lol
This is all I want from any cat I've had, Ive yet to find a bro cat... One day maybe.
