Suppose 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. An equal situation holds for B-,C- and D-. The cross AA BB CC DD (female) x aY bb cc dd (male) ismade.
A) probability of obtaining A- individual in F1
B) probability of obtaining an a male in the F1 progeny
C) Probability of A- B- C- D- female in F1
D) How many different F1 genotypes are there?
