In drosophila, the autosomal recessive brown eye color mutation displays interactions with both the x- linked recessive vermilion mutation and the autosomal recessive scarlet 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. predict the fl and f2 progeny of crossing the following true-breeding parents: a. vermilion females x brown males b. brown females x vermilion males c. scarlet females x brown males d. brown fem ales x scarlet males
