The Soay sheep of St. Kilda Island near Scotland have changed coat color over the past 20 years, with dark colored sheep declining in frequency and light colored sheep increasing. Coat color is determined by the TYRP1 gene. The TYRP1-T homozygote is light colored, while TYRP1-G homozygotes and heterozygotes are dark. Discuss the hypothesis that assortative mating between sheep with similar coat color is the cause of the increase in light coat color over this period.
