    You’re assuming that the aliens’ vision can’t detect our stripes.

      It can’t, because in the overwhelmingly vast majority of people, there are no visible lines in any way. What’s there is a shift of skin cell patterns, but unless the alien has a microscopic zoom eye that sees individual cells, thats not visible. MRI vision would also work, or other active detection methods that can see past the visible surface.

      There are certain skin conditions that can make the lines visible, and some conditions that can bring them out under UV light or other wavelengths. But apart from very specific individuals, no light can detect the stripes.

    Hey what about us mixed-race people? If the genes fell just right, would the stripes be visible on us?

      It seems that because skin color in humans is determined by more than just the X chromosomes in skin cells, this is not the case. However it is the case in some animals, such as cats, which is why calico cats look like they do.

      If skin color in humans was due to solely that X chromosome, then yes, at least theoretically a person who’s parents have different skin colors would present both of those colors along these patterns. It would probably be most noticable on mixed-race people but technically almost everyone would have something similar unless both of your parents had the exact same shade of skin color. I think it’d be cool!

      They’re called Blaschko’s lines.

      Here’s an article with some great pictures showing how stripes show up on humans, which are invisible normally, but can be seen due to certain skin conditions.

        Interesting, the lines look very similar to the dermatomes. At least the ones I’m familiar with due to herniated discs.

    There’s genetic code that’d give them stripes but they’re just the same colour as the rest of the skin

    Ergo they’re not stripes.

    That’s like saying paper has stripes because it’s made from fibers of many different trees but since it’s bleached (and also since tree fibers tend to look the exact same) you can’t see them.
