Problem 5-35: Two genes control color in corn snakes as follows: O- B- snakes are brown, O- bb are orange, oo B- are black, and oo bb are albino. An orange snake was mated to a black snake, and a large number of F1 progeny were obtained, all of which were brown. When the F1 snakes were mated to one another, they produced 100 brown offspring, 25 orange, 22 black, and 13 albino. a. What are the genotypes of the F1 snakes? (1 point) b. What proportions of the different colors would have been expected among the F2 snakes if the two loci assort independently? (1 point) c. Do the observed results differ significantly from what was expected, assuming independent assortment is occurring? What is the probability that differences this great between observed and expected values would happen by chance? (3 points)
