Question
A system of sex determination known as haplodiploidy is found in honeybees. Females are diploid, and
males (drones) are haploid. Male offspring result
from the development of unfertilized eggs. Sperm are
produced by mitosis in males and fertilize eggs in the
females. Ivory eye is a recessive characteristic in
honeybees; wild-type eyes are brown.
a. What progeny would result from an ivory-eyed
queen and a brown-eyed drone? Give both genotype and
fertilized and nonfertilized eggs.
b. What would result from crossing a daughter from
the mating in part (a) with a brown-eyed drone?
