Question

A dam breaks, separating a population of dung beetles into one large group and one much smaller group. This species of dung beetle only reproduce once a year and females typically only produce one or two offspring.

What type of isolation is this called?
What group runs the greater risk of decreased genetic diversity/variation?

Answer 1

Hope this helps :)
