What Causes the Reproductive Isolation That Can Lead to Speciation

Question

What causes the reproductive isolation that can lead to speciation?
A) Members of one group don't want to mate with other groups.
B) Members of one group are unable to make fertile offspring with other groups.
C) A group is extinct.
D) Some members of a group are sterile.

Accepted Answer

Reproductive isolation occurs when members of different groups are unable to produce fertile offspring with one another. This can be due to differences in genetic makeup, behavior, or physical characteristics, and can lead to the development of new species over time. Factors like geographic isolation or disruptive selection can also contribute to reproductive isolation and eventual speciation.
