#i'm increasingly convinced that micromosaicism (likely including microchimerism) isn't rare at all. but it's usually invisible

is antpelt's single black ear a realistic somatic mutation?

I have no idea how realistic it is, but i can imagine it happening.

Brown with a black ear... you know how i'd do this? I'd make him a tabby carrying solid (usually make canonically brown cat black tabbies anyway), then make a somatic mutation that results in losing the chromosome part that has the tabby allele. If everything is well and no genes are lost for which it's vitally important to have two copies (no idea how plausible that is), you can have a small solid black patch.

I had a class about a related topic a few weeks ago, so it's still vivid 😸 University is so useful! I can use what i learn to make warriors headcanons

Mosaicism as the result of incorrect chromosome segregation.
