Determine an algebraic expression for the probability of each genotype in terms of p (the probability of inheriting D) and q (the probability of inheriting d). Use the Punnett square above as a guide.

a. In terms of p and q, what is the probability of a DD offspring?
b. In terms of p and q, what is the probability of a dd offspring?
c. In terms of p and q, what is the probability of a Dd offspring?
