In the fruit fly drosophila, there is a dominant gene for normal wing shape and its recessive allele for dumpy wings. at another gene locus on the same chromosome, there is a dominant gene for tan body color and its recessive allele for ebony body color. a male that is homozygous for both dominant alleles is crossed with a female that is homozygous for both recessive alleles. what percentage of the f1 flies are expected to be heterozygous at both gene loci? ( enter the number only without the percent sign. for example, enter 100% as 100 and enter 12.5% as 12.5 )
