Problem 1 In sheep, the allele for black wool (B) is dominant over the allele for white wool (b). Similarly, the allele for horns (H) is dominant over the allele for being hornless (h). Pure breeding horned sheep with black wool were crossed with pure breeding hornless sheep with white wool. 1. State the genotype and the phenotype of the F1 individuals produced as a result of this cross. 2. Two F1 offspring were mated together. Calculate the expected ratio of phenotypes in the F2 generation.

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.
