Genomic analyzes of the apple- and hawthorn-feeding races of Rhagoletis suggest that genetic divergence between the two species has largely been driven by ____ selection, a diversifying form of natural selection.
A) disruptive
B) directional
C) stabilizing
D) artificial
E) sexual

Question

Quizplus · Accepted Answer

Disruptive selection is a type of natural selection that simultaneously favors individuals at both extremes of the distribution. In the case of Rhagoletis, the apple- and hawthorn-feeding races have adapted to different host plants, leading to genetic divergence between the two groups. This divergence is a result of disruptive selection, where the extreme traits (preference for apple vs. hawthorn) are favored over intermediate traits, driving the two races apart genetically.
