4. In Drosophila, eye color is determined by two different genes located on different chromosomes. A recessive gene b, found on the second chromosome, produces brown eye color. The second chromosome is an autosomal chromosome. A recessive sex-linked gene v causes vermilion eye color to be produced. The presence of the dominant genes B and V results in a wild-type color. The presence of both the brown and vermilion allele, in the homozygous condition result in an individual with white eyes. Indicate the genotypes and phenotypes produced from the following crosses: a) BBVV(wild-type female) x bbvY(white-eyed male) b) BbVv ( wild-type female) x BBVY (wild-type male) c) bbVV ( brown-eyed female) x BbvY (vermilion-eyed male)
