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). a. What gametes can be formed with respect to these genes by a heterozygous, brown-eyed, color-blind male? b. If a blue-eyed mother with normal vision has a brown-eyed, color-blind son and a blue- eyed, color-blind daughter, what are the genotypes of both parents and children? If the dominant allele A is negeceary fos oarino.
