I thought that Hardy-Weinberg equilibrium's assumption was...

No natural selection
No Mutation
No migration (which means population must be "isolated")
large population
random mating

So, I was pretty sure that a) no isolation isn't assumption.

But, Destroyer says it is.

I am confused...:scared:

Think of it this way. You have one population. There is no migration, meaning other populations can't come in and disturb your genes.

Isolation would mean that a certain group of your population gets isolated, not that your entire group is isolated from others. If a part of your group was isolated, they would evolve differently then the rest of the group. Thus, no isolation.

and thats called sympatric speciation...allopatric is when species evolve differently based on isolation due to land barriers- just a side note...never know when it will pop up

Oh, now I got it. I thought that was whole population. But it wasn't.

Thanks!

I would've been confused by that problem. Poor wording.

also isolating a subpopulation would de-randomize the mating
