Which of the following is an example of a postzygotic reproductive barrier?
a. One Ceanothus shrub lives on acid soil, another on alkaline soil.
b. Mallard and pintail ducks mate at different times of year.
c. Two species of leopard frogs have different mating calls.
d. Hybrid offspring of two species of jimsonweeds always die before reproducing.

Accepted Answer

Hello everyone here We have a question that says the hybrid and viability and hybrid sterility produced from mating. Two different species is an example of a pre psychotic barrier. A pre psychotic barrier prevents members of different species from mating to produce a zero. So A. Is incorrect. Be post psychotic barrier. Post psychotic barrier is a mechanism that blocks reproduction after fertilization and zygote in formation so B. Is correct. See temporal isolation. Temporal isolation prevents the interbreeding of closely related species, so C. Is incorrect. And D reproductive specialization, reproductive specialization is when the species has certain things they look for when reproducing and the other species does not have those so D. Is incorrect. So our answer here is the post psychotic barrier. Thank you for watching. Bye.
