Root Explanation

Diploidy is formed from "di-" (meaning two) and "ploides" (from Greek "ploides", meaning fold or layer). The term refers to the condition of having two sets of chromosomes, hence the concept of two layers or folds of genetic material.

Memory Tip

Think of 'di-' meaning two, and 'ploides' relating to layers — diploidy describes having two layers of chromosomes.
