a. limited hybrid fertility
b. limited hybrid viability
c. hybrid breakdown
d. gametic isolation

Accepted Answer

Hello everyone and welcome to today's video. So mating closely related species of animals often results in in viable or sterile hybrids. This can reduce the exchange of genetic variants between species. This general consequence brought about this process is called, well remember that we have hybrids that result from different species. Remember that different species are not supposed to make together. So nature, in order to prevent this is going to be making the hybrids in viable or or sterile, as the question says. So these hybrids are either gonna be inviolable, they're going to die young or they're going to be sterile. They kind of produce more hybrids. And this collection of prevention methods by nature is going to be called hybrid incompatibility, which is going to be represented by answer choice B. I really hope this video helped you and I hope to see you on the next one.
