In Drosophila, eye color is related to two genes and each gene has two alleles, one for a functional protein and one for a nonfunctional protein. Both genes must have at least one dominant allele to make a functional red pigment; otherwise, the eyes will be white. If a fly is homozygous for either recessive allele (a or b), it will have white eyes. A geneticist has two pure-breeding strains of white-eyed Drosophila. If a complementation test reveals that the strains complement, which result would you expect?
