Summary

Drones have a unique family tree structure, with only one parent. This is reflected in the Fibonacci sequence, where each level of ancestors is a Fibonacci number.

For example, a drone has one parent, two grandparents, three great-grandparents and so forth.

This pattern is particularly impressive in the reproduction of bees, where male honey bees, called drones, only have one parent.

According to

Summary
The female bees (queens and workers) have two parents: a drone and a queen. Drones, on the other hand, hatch from unfertilized eggs. This means they have only one parent. Therefore, Fibonacci numbers express a drone's family tree in that he has one parent, two grandparents, three great-grandparents and so forth [source: Knott ]
