The Hairless phenotype in Drosophila is caused by a recessive mutation in the H gene. Wild-type Drosophila have hair on all body segments. Two heterozygous Hh Drosophila are crossed: 25% of the offspring have normal hair on their bodies and 25% have no hair at all. 50% of the offspring have less hair on their bodies than wild type, and the amount of hair they have varies. The Hairless phenotype in Drosophila displays what relationship between alleles?     Incomplete penetrance Incomplete penetrance Codominance Codominance Incomplete dominance Incomplete dominance Variable expressivity Variable expressivit
