Suppose a gene A is on the X chromosome, and genes B, C, and D areon three different autosomes. Thus, A- signifies the dominantphenotype in the male or female. A equivalent situation holdsfor B- C- and D-. The cross AA BB CC DD female crossed withaY bb cc dd male is made.

1) What is the probability of obtaining an A- individualin the F1 progeny.

2) What is the probability of obtaining an "a" male inthe F1 progeny.

3) What is the probability of obtaining an A- B- C- orD- female in the F1 progeny.

4) How many different F1 genotypes will there be?

5) What proportion of the F2 individuals will beheterozygous for the four genes?
