Scientists have hypothesized that the reason European men have darker skin color than European women is that more than 10,000 years ago, these men preferred to mate with lighter-skinned females. If this is true, skin color is an example of _____ in Europeans.
A)gene flow
B)a genetic bottleneck
C)sexual selection
D)recombination

Question

Quizplus · Accepted Answer

Sexual selection is the process by which certain traits become more prevalent in a population due to the preference of certain individuals for those traits in potential mates. In this case, if European men preferred to mate with lighter-skinned females, it would result in a greater prevalence of lighter skin color in women as opposed to men. This is an example of sexual selection. Gene flow refers to the transfer of genetic material between populations, a genetic bottleneck is a sharp reduction in the size of a population leading to decreased genetic diversity, and recombination is the process by which genetic information is exchanged between paired chromosomes during meiosis. None of these are applicable to the scenario presented.
