The example of the Agouti gene in snowshoe hares shows that

A) natural selection can rapidly spread an allele introduced into a species by hybridization.
B) the effect of natural selection can change in response to the changing climate.
C) a and b
D) none of the above

Agouti Gene

A gene that influences pigmentation patterns in mammals' fur by controlling the distribution of melanin.

Snowshoe Hares

A species of hare native to North America, known for their large hind feet and seasonal color change from brown to white.
