Photoset reblogged from Hopeful Veterinarian with 206 notes
now chimerism is the coolest BECAUSE it’s when one embryo fucking engulfs the other and so you see traits that would normally never come together, like brindling and mosaic paints and calico paints
also it’s non inheritable, because the horse has two sets of genes and they’re all mix matched
it can also occur genotypically but not phenotypically
so it’s like you have a black horse produce a pangare and it’s like wtf
but he might’ve been a chimera and had the pangare gene from his twin and it’s just like isn’t that fucking cool
okay just let me talk about horse genes to myself
