Honeybees are unusual in that male bees (drones) have only onecopy of each gene, but female bees have two copies of their genes.This difference arises because drones develop from eggs that havenot been fertilized by sperm cells. In bees, the trait of long wingsis dominant over short wings, and the trait of black eyes is dominant over white eyes. If a drone with short wings and black eyeswas mated to a queen bee that is heterozygous for both genes, what are the predicted genotypes and phenotypes of male and femaleoffspring? What are the phenotypic ratios if we assume an equalnumber of male and female offspring?

Question

Honeybees are unusual in that male bees (drones) have only one
copy of each gene, but female bees have two copies of their genes.
This difference arises because drones develop from eggs that have
not been fertilized by sperm cells. In bees, the trait of long wings
is dominant over short wings, and the trait of black eyes is dominant over white eyes. If a drone with short wings and black eyes
was mated to a queen bee that is heterozygous for both genes, what are the predicted genotypes and phenotypes of male and female
offspring? What are the phenotypic ratios if we assume an equal
number of male and female offspring?
