Q. Two genes organize in corn snakes as follows: O-B is brown snakes, O-bb are orange, 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 offsprings, 25 orange, and 22 black and 13 albinos. What are the genotypes of the f1 snakes? What proportions of the dissimilar colours would have been expected among the F2 snakes if the loci assort independently? Do the observed result differ significantly from what was expected, assuming independent is occurring? What is the possibility that differences this great between observed and expected values would happen by chance?
