In horses, there are three coat colour patterns called cremello (beige/light brown), chestnut (brown) and palomino (golden with a light mane and tail). If two palomino horses are mated, they produce about % cremello, 3. 4 chestnut and % palomino offspring. In contrast, cremello and chestnut horses breed true. Explain this pattern of inheritance. (Refer to the number of loci controlling the trait, the number of alleles per locus and the dominance interaction between the alleles). a. b. Assign genotypes to the phenotypes.

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.
