2. Listed below are 5 of the modified 9:3:3:1 ratios observed for the F2 progeny from dihybrid parents. Suppose that for each one, one of the dihybrid parents is testcrossed to the double recessive individual, rather than to another dihybrid individual. What phenotypic ratio is expected in the progeny of each testcross? [hint: figure out which of the numbers (out of 9:3:3:1) are combined to make each ratio below. For each combination, the SAME phenotype classes will be combined for the testcross.] a. 9:6:1 b. 9:3:4 c. 9:7 d. 12:3:1 e. 13:3
