Refer to the experiment conducted by Gregor Mendel in Exercise 4.64. Suppose you are interested in following two independent traits in snap peas-seed texture (S = smooth, s = wrinkled) and seed color (Y = yellow, y = green)-in a second-generation cross of heterozygous parents. Remember that the capital letter represents the dominant trait. Complete the table with the gene pairs for both traits. All possible pairings are equally likely.

a. What proportion of the offspring from this cross will have smooth yellow peas?
b. What proportion of the offspring will have smooth green peas?
c. What proportion of the offspring will have wrinkled yellow peas?
d. What proportion of the offspring will have wrinkled green peas?
e. Given that an offspring has smooth yellow peas, what is the probability that this offspring carries one s allele? One s allele and one y allele?
