Eli5: How much of a species’ sequenced genome is stable enough to represent a species, as opposed to finer stuff that will keep changing really fast as they breed?

Question

I know this would vary a lot between species, so for example, what’s this like in the human genome?

In: Biology

Answer 1

It’s also worth noting that gene pool diversity can vary a lot between species. Those that recently experienced near extinction, like humans, have much less variation between individuals. Self cloning species, like marble crayfish, show essentially none.
