Factors A, B, C, D cont the production of a black pigment. The genes encoding A, B, C and D are independently assorting. The alternate alleles that give abnormal function of these genes are a, b, c, and d. A black AA DD is crossed with a colorless aa bb cc dd to give a black FI. The FI is then d with a colorless aa bb cc dd.
Assume that A, B, C and D act in a pathway as follows: colorless colorless grey brown black
What percentage of the F2 are black?
Choose one:
a. 1/4
b. 1/6
c. 1/8
d. 1/16
e. None of above
