Question

Which of the following is a post-zygotic reproductive barrier between species?

Group of answer choices

living in different habitats

mating at different times

All the answers are correct

having different mating behaviors

hybrid infertility

Answer 1

Answer=hybrid infertility

Explanation-

Reproductive Isolation mechanism restricts (Block) the genetic exchange between the individuals.The reproductive Isolation mechanism is based on biological and behavioral characters that prevent interbreeding among the related population.

There are two types of reproductive Isolation(barrier)-

1) Pre-zygotic Reproductive barrier

2)Post-zygotic Reproductive barrier

Hybrid infertility comes under Post-zygotic Reproductive barrier in which normal maturation process doesn't take place and they are sterile so does not produce viable gametes.

Now consider other option-

Living in different habitats,mating at different times and having different mating behaviors are categorised under pre-zygotic reproductive barrier between species.
