In humans, red-green color blindness is determined by an X-linked recessive allele (a), whereas eye color is determined by an autosomal gene, where brown (B) is dominant over blue (b).What gametes can be formed with respect to these genes by a heterozygous, brown-eyed, color-blind male? A) BX^a, BY B) bX^a, bY C) BX^a, bY D) BX, BY, bX, bY E) BX^a, BY, bX^a, bY

A heterozygous, brown-eyed, color-blind male has the genotype X^aBY. He can produce gametes with either the X^a chromosome or the Y chromosome, and either the B allele or the b allele. Therefore, he can produce the following gametes: X^aB, X^ab, Y, and Y.
