Asked by a

hich evidence would BEST support the claim that the phenotypes of these populations of mice are a result of natural selection?
A
A mutation in the same gene led to the coastal populations having the same coat color.
B
An allele for light coat color is more common in the coastal populations than the inland population.
C
The genes that code for a light coat color have been lost from the inland population.
D
The coastal and inland populations all share the same alleles for coat color.

B

Natural selection changes allele frequencies so that alleles that increase fitness are more common in the environments where they are advantageous. Finding the light‑coat allele at higher frequency in coastal populations than inland populations is direct evidence of selection favoring that phenotype there.

(A) could reflect a founder event, (C) suggests loss (drift or bottleneck), and (D) argues against genetic differences driving the phenotypes.
