Question

In Drosophila, the autosomal recessive brown eye color mutation (b) displays interactions with both the X-linked recessive vermilion mutation (v) and the autosomal recessive scarlet (s) mutation. Flies homozygous for brown and simultaneously hemizygous or homozygous for vermilion have white eyes. Flies simultaneously homozygous for both the brown and scarlet mutations also have white eyes. Flies that are wildtype at all 3 loci have wildtype eye color. Flies that are homozygous or hemizygous for the recessive mutant at only one locus show that mutations color. (i.e. brown, vermillion or scarlet).
