In humans, male pattern baldness is due to an autosomal locus where bald is dominant in males and recessive in females. Let B represent the bald allele and "b" represent the non-bald allele in this problem. Albinism is an autosomal recessive disorder that results in a lack of melanin. Let "a" represent the albino allele and "A" represent the normal pigment allele for this locus. A male who is heterozygous for both loci marries a female who is also heterozygous for both loci. Complete the blanks in the phenotypic ratio below with whole numbers to indicate the phenotypic ratio of the progeny expected from this cross. Be sure that your ratio is in lowest possible form.
_ I have the dihybrid cross but im stuck at trying to fiqure out what sex has what genotype. How do i do that with autosomal traits?
