Question

Two species of frogs mate with each other. The embryo dies after a few cell divisions. What kind of reproductive isolation does this example represent?

A.
temporal isolation
B.
mechanical isolation
C.
postzygotic isolation
D.
gametic isolation

Answer 1

The correct answer is B, mechanical isolation. We know that mechanical isolation prevents two species’ gametes from successfully combining to form a healthy embryo. I hope I helped! :)
