Which of the following is the most predictable outcome of increased gene flow between two populations?
A) lower average fitness in both populations
B) higher average fitness in both populations
C) increased genetic difference between the two populations
D) decreased genetic difference between the two populations

Question

Quizplus · Accepted Answer

Increased gene flow means there is more migration of individuals between the two populations. This results in a higher sharing of genetic material between them, leading to a decrease in genetic differences. Therefore, option D is the correct answer. Option A would only occur if gene flow introduced harmful alleles. Option B is not always true and is dependent on the genetic makeup of the populations. Option C is the opposite of what happens with increased gene flow.
