Human women have stripey skin too, but you can't see it under normal light because unlike cats, skin tone in humans is not controlled by the X chromosome.

Can you link to a scientific article? I have severe doubts about that claim made on a random youtube video. In fact, I'd go as far as to claim that the content of the words here, are not correct. This is why I think a doi link to a research paper is necessary. I don't doubt that individual cells are, of course, chimeric, but I doubt the "stripey skin" claim. That one makes zero sense.

I just did a google search and this further confirms my suspicion. Thus I would like to ask for a link to a scientific article - until that happens I remain rather unconvinced.

I haven’t read it but I did find this

I agree about the need for verification, but Veritasium videos are usually well-researched and more accurate than "random" videos.

Here's one link:

Humans have 'stripey' skin because of somatic mutations, and it's not clear that there are X-chromsome-located skin color loci. Don't believe everything you see on Youtube.

That video seems to imply you can't see it under any light and the image there is pure visualization.

AFAIR this comes up visually when infected with certain diseases.

For a more practical example, how does this work for the daughter of a colorblind person (the colorblindness gene is on the X chromosome)? Do they have four types of cones?

Yes, but it's not limited to that case - there's two common variants of the green cone that respond to different wavelengths and people with two X chromosomes can have both, improving colour identification.

Genetics is complicated.

If you really want to learn about this, all you need to do is search.

I'm kind of late to this but for some context - bonzini knows me from a long time ago when I was still a genetics student and the joke here is that given where I am now in my career I still get to occasionally answer questions based on that background
