Question

Different mating habits cause two groups within a population to be less likely to mate with each other. As a result, reproductive isolation occurs between the two groups. What does this cause?
A. An increase in genetic drift.
B. An increase in gene flow.
C. A decrease in genetic drift.
D. A decrease in gene flow.

Answer 1

Answer:

increase in genetic drift

Answer 2

Option A is the correct answer.

The cause is an increase in genetic drift.

Explanation:

• Different mating habits are categorized into two groups where within a population it is less likely to mate with each other.
• There occur two types of divergence basically the genetic and phenotypic divergence
• This is between populations that affect characters that influence reproduction.
• If the individuals of the two populations are to be brought together, mating would be impossible, and if mating occurs, then the offspring would be non-viable or infertile.

• If the populations are to genetically diverge from one another, they must have a limited number of gene flow between them.

• Reproductive isolation occurs between the two groups with an  increase in genetic drift
