In maize, a dominant allele A is necessary for seed color, as opposed to colorless (a). Another gene has a recessive allele wx that results in waxy starch, as opposed to normal starch (Wx). The two genes segregate independently. An Aa WxWx plant is test crossed. What are the phenotypes and relative frequencies of offspring? (show the workflow to reach your answers)

A man suffered from rare a skin condition that included thickening of the skin and the formation of loose spines that were periodically sloughed off. He was called by the locals as “porcupine man”. He married and had six sons, all of whom had the same condition. He also had three daughters, all of whom were unaffected.

all sub-questions carries equal grades): Consider three gene pairs Aa, Bb, and Cc, each of which affects a different character. In each case, the uppercase letter signifies the dominant allele and the lowercase letter the recessive allele. These three gene pairs assort independently of each other. Calculate the probability of obtaining the following (show the workflow to reach your answers):
