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.

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
