Root Explanation

Homolog is formed from "homo-" (from Greek "homos", meaning same) and "logos" (from Greek "logos", meaning word or reason). The term refers to things that are the same or similar in structure or function, often used in biology to describe similar traits in different species.

Memory Tip

Think of 'same' ('homo-') and 'word' or 'reason' ('logos') to remember that homolog refers to things that are similar or the same in structure or function.
