Question

What must occur within a gene pool before the formation of a new species? a. geographic isolation b. niche formation c. reproductive isolation d. speciation

Answer 1

C; Reproductive isolation must occur before the formation of a new species.

Answer 2

Answer: c. Reproductive isolation

Explanation:

The reproductive isolation can be define as the barrier in reproduction between the members of the same species. This can be because of difference in behavior, morphology, adaptations, physiology and even at the genetic level. This leads to the development of new species due to reproductive isolation. This process is known as speciation.
