Root Explanation

Epistasis → It is formed from "epi-" (meaning upon or over) and "stasis" (from Greek "stasis", meaning standing or stability). The term describes a genetic phenomenon where one gene's expression is affected by another gene, thus standing over or upon the effects of another.

Memory Tip

Think of a gene that stands 'upon' ('epi-') another gene's effects, influencing its expression — that's what epistasis means.
