Root Explanation

Recessive → It is formed from "re-" (meaning back or again) and "cedere" (meaning to go or yield). The word "recessive" describes a trait that yields or goes back in the presence of a dominant trait.

Memory Tip

Think of a trait that 'yields back' ('re-') when faced with a stronger one ('cedere'). This helps you remember that 'recessive' refers to traits that are not expressed when a dominant trait is present.
