In goats, a beard is produced by an autosomal allele that is dominant in males and recessive in females. We’ll use the symbol Bb for the beard allele and B+ for the beardless allele. Another independently assorting autosomal allele that produces a black coat (W) is dominant over the allele for a white coat (w). Give the phenotypes and their expected proportions for the cross between B+Bb Ww male × B+Bb Ww female.
Which of the following is not an option phenotype and proportion from this cross?
a. 9/16 bearded, black female
b. 3/16 bearded, black female
c. 1/16 beardless, white male
d. 3/16 bearded, white male
e. 1/16 bearded, white female
