Answer 1

A. reproductive isolation resulting in two separated gene pools.

Step-by-step explanation:

This occurs when there are two different genes that somehow get separated. This separation can be either physical separation or they just cannot reproduce together anymore. A gene pool is one type of gene for a certain trait. Blonde hair and red hair are both separate gene pools for hair color.
