Root Explanation

Heterozygosis → It is formed from "hetero-" (from Greek "heteros", meaning different) and "zygos" (from Greek, meaning yoke or pair). The term refers to a condition in which an organism has two different alleles for a particular gene, hence the idea of being yoked or paired with different forms.

Memory Tip

Think of 'different' ('hetero-') paired together ('zygos') — that's why heterozygosis refers to having different alleles paired in genetics.
