Please do expand on "It's more about the nature of the mutations".
How long have you got? You can learn all about it at many good colleges and universities, and even at quite a few rubbish ones.
Put simply, there are some areas in which mutations will produce incompatibility in only a few generations. It's only incompatibility denying gene flow that matters. It isn't remotely about absolute numbers. It's a fairly simple point, and should require no elaboration.
