Assuming the threshold model applies to this kernel color system, what proportion of the progeny of the cross G1G2M1M2T2T2 ×× G1G2M1M2T1T2 do you expect to display colored kernels? Assuming the threshold model applies to this kernel color system, what proportion of the progeny of the cross G1G2M1M2T2T2 G1G2M1M2T1T2 do you expect to display colored kernels? 1212 of the progeny will be white and 1212 will be colored. 1414 of the progeny will be white and 3434 will be colored. 3434 of the progeny will be white and 1414 will be colored. None of the progeny will be colored.1. Two trihybrid plants are mated. What is the expected proportion of progeny plants displaying 9 units of color?2. Suppose that instead of an additive genetic system, kernel-color determination in this organism is a threshold system. The appearance of color in kernels requires 9 or more units of color; otherwise, kernels have no color and appear white. In other words, plants whose phenotypes contain 8 or fewer units of color are white. Based on the threshold model, what proportion of the F2 progeny produced by the trihybrid cross in part (1) will be white?a. 1/8b. 24/64c. 1/4d. 22/64
