Question
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?
b. What proportions of the different colors would
have been expected among the F2 snakes if the two
loci assort independently?
