Solution
Most of the variation we see in coat colouration and pattern in a population of wild mustangs in any generation are probably due to sexual recombination of alleles.
Explanation:
Sexual recombination during gamete formation and fertilization leads to new combinations of alleles, generating genetic variation in offspring. This genetic variation manifests as differences in traits such as coat color and pattern within the population from generation to generation. While genetic drift and geographic variation can influence population genetics, and environmental effects can cause some phenotypic variation, the primary source of the heritable variation seen generation to generation in such traits is sexual recombination of alleles.
