Reproductive Isolating Mechanisms

[azarbock]

I was reviewing for a test when I came across the following piece of information to study:

" List and describe how any 3 reproductive isolating mechanisms function to maintain species boundaries. "

Would this refer to pre-zygotic mechanisms (ecological, temporal, behavioral, etc.) or post-zygotic mechanisms (hybrid inviability, hybrid sterility, and hybrid breakdown)? Thanks!

Since both pre-zygotic and post-zygotic mechanisms work to preserve species boundaries, I think that either would work as answers.

I just saw your location. I'm originally from a town very near Asheville. Neat.

Thanks for the help! I'll use both the pre and post-zygotic mechanisms to study. Representing Western N.C.
