1. For a single locus with two alleles, A₁ and A₂: (a) Draw a graph (using graph paper) showing both the frequency of A₁ A₂ heterozy- gotes and A₂ A₂ homozygotes, at Hardy-Weinberg frequencies, as functions of p (the frequency of A₁). Note that both p and the genotype frequencies should have values between 0 and 1. (b) Find the value of p above which A₁ A2 genotypes are more common than A2A2 genotypes. You can solve this algebraically, or estimate it from your graphs.

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.
