Question

What keeps the two populations separate?

1) temporal reproductive isolation
2) lack of hybrid viability
3) behavioral reproductive isolation
4) habitat isolation

Answer 1

Reproductive isolation, such as temporal reproductive isolation, lack of hybrid viability, behavioral reproductive isolation, and habitat isolation, keeps two populations separate.

Step-by-step explanation:

Reproductive isolation keeps two populations separate. There are several forms of reproductive isolation including temporal reproductive isolation, lack of hybrid viability, behavioral reproductive isolation, and habitat isolation.

Temporal reproductive isolation occurs when two species have different breeding schedules, such as one species reproducing in January to March and the other in March to May.

Lack of hybrid viability is when the offspring of two different species are weak or unable to survive.

Behavioral reproductive isolation happens when there are differences in courtship rituals, mating behaviors, or other behaviors that prevent mating between two species.

Habitat isolation occurs when two species occupy different habitats and therefore do not come into contact with each other to reproduce.
