In fruit flies (drosophila melanogaster) there is a dominant allele for red eyes and a recessive allele for white eyes. these alleles are located on the x chromosome. if a heterozygous red-eyed female is mated with a white-eyed male, what percentage of the offspring are expected to be white-eyed females? ( enter the number only without the percent sign. for example, enter 100% as 100 and enter 12.5% as 12.5 )
