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 white coat (w). A cross allowed between BBbWw (male) X BBbWw (female). What is proportional of female progeny will beard with black coat?
