2. Eye color in humans: At least two pairs of genes control eye color. Both pairs influence the production of the pigment, melanin, but act independently. One pair of alleles is B (Brown color; dominant) and b (blue color); the other pair is A (pigment production; dominant) and a (no pigment production; albino). The gene pair aa is epistatic to (masks) B and b and produces the nonpigmented eyes of the albino. a. Give the genotypes and phenotypes of the possible offspring of the mating bbAa Bbaa and indicate the parents phenotypes..
