Comment on Evolution without sex: How asexual mites generate genetic diversity and ensure survival

For instance: In cats, a big part of their skin pigmentation is controlled by the X chromosome. Which is why you’ll only find female calico cats. Males only carry the one X and can only manifest one color pattern.

just to be contrarian I had a male calico, and I also had a female orange (full) cat. But I get your meaning and I think I was saying the same thing. The skin is doing its thing long before the other X is decided which would then set a lot of the bones and features that I think get set after one has shut down (sorry if it came off like I didnt mean this).

Your male calico is likely intersex XXY. very rare.
Sorry, I had indeed misinterpreted your previous comment. Thanks for clarifying.

It was only a small eraser sized grey dot in a other wise orange tabby white mix. His name was Ru after Ru-paul and he was fabulous.
