What is haplodiploidy, and how is it related to altruism in honeybees?
What will be an ideal response?
Drones (male bees) are haploid, while queen bees are diploid. Worker bees are either 50 percent or 100
percent related to each other, depending on whether they share the same alleles from their mother.
Nonreproducing workers help to pass alleles they share into the next generation by caring for their
siblings.
