Honey Bees are unusual in that male bees (drones) have only one copy of each gene, while female bees have two copies of each gene. That is because drones develop from eggs that have not been fertilised by sperm cels. 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?

Honeybees are unusual in that male bees (drones) have only one copy of each gene,
while female bees have two copies of each gene. That is because drones develop
from eggs that have not been fertilised 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?
