The haplodiploid social structure of some insect colonies influences kin selection and worker behavior.

A haplodiploid may produce male offspring from unfertilized eggs while females develop from fertilized eggs.

Haplodiploids like many bees and ants present interesting challenges for kin selection theory.

Many researchers study haplodiploidy because it explains why males in some insect species develop from unfertilized eggs and are haploid while females develop from fertilized eggs and are diploid.
