The presence of a beard on some goats is a sex-influenced characteristic determined by an allele at an autosomal locus Bb. In males, this allele is dominant and in females this allele is recessive. If you cross a homozygous bearded male with a heterozygous beardless female, what are the expected phenotypes for males and females?

From the previous question of the martian family, what is/are the genotype(s) of the mother and brother’s mother?   (Here’s the question again so that you don’t have to go back: A recently found martian family is under study. According to early studies, it was found that D (dextral) is dominant to d (sinistral). The mother and her brother, both have genotype Dd and are sinistral. The father of the family (not their father, but the mother’s husband) is dextral, with the genotype dd. All of their offspring are dextral. )
