Blue light is that portion of the visible spectrum that penetrates the deepest into bodies of water.Ultraviolet (UV)light,though,can penetrate even deeper.A gene within a population of marine fish that inhabits depths from 500 m to 1000 m has an allele for a photopigment that is sensitive to UV light,and another allele for a photopigment that is sensitive to blue light.Which of the following graphs best depicts the predicted distribution of these alleles within a population if the fish that carry these alleles prefer to locate themselves where they can see best?
