Match each example to one of the processes below.

Question

Quizplus · Accepted Answer

This example is best explained by natural selection because the dark rocks provided a selective advantage to dark-colored mice and the light rocks provided a selective advantage to light-colored mice.

Answer: C 
 This example is best explained by the founder effect because the mouse populations on the dark and light rocks were originally part of a larger population that became separated, causing genetic differences to become amplified in each group.

Answer: A 
 This example is best explained by genetic drift because it involves random changes in allele frequency that can lead to differences between populations over time.

Answer: D 
 This example does not fit any of the processes listed. Gene flow refers to the movement of genes between populations, but there is no indication in the example that genes are moving between the dark and light rock mouse populations.
