In hybrid zones where reinforcement is occurring, you should see a decline in

D) hybrid sterility.
E) the genetic distinctness of two gene pools.

Question

Quizplus · Accepted Answer

Reinforcement typically involves the strengthening of reproductive barriers between two distinct gene pools. This can lead to a reduction in gene flow between these groups, as natural selection favors those individuals that are less likely to mate with hybrids. As gene flow declines, the genetic distinctness of the two gene pools may increase, but this is not always the case. Hybrid sterility may or may not be involved, depending on the specific mechanism of reinforcement. Speciation and mutation rates may also be impacted, but these are not necessarily related to reinforcement.
