Ants and bees in a hive have very similar genetics. Typically 75%, and sometimes 100%, if I remember.

This means that a hive in some ways is best thought of as a single organization, which happens to have a "distributed" body.

In that view, the non reproducing individuals are propagating their DNA in the same sense that human liver cells do, even though they don't have the direct involvement that down and egg cells do.
