Multiple Choice
Pea aphids (Acyrthosiphon pisum) are the only animals able to synthesize their own carotenoid pigments, due to lateral gene transfer from the genome of a fungus to the genome of a recent ancestor of the pea aphids. The resulting red or green coloration alters the risk the aphids face from specific predators and parasites. Select the correct statement below.
A) The lateral transfer of genes for carotenoid synthesis had a deleterious effect on the aphid genome.
B) Natural selection favored the lateral transfer of genes for carotenoid synthesis from a fungus to an aphid.
C) The lateral transfer of genes for carotenoid synthesis from a fungus to an aphid is a form of mutation.
D) The lateral transfer of genes for carotenoid synthesis occurred to provide the aphids with protection from their predators and parasites.
