Definition

A type of gamete that is different in structure or function from another gamete, typically referring to the smaller, mobile male gamete and the larger, non-mobile female gamete.

Example

In many species, the male and female gametes are heterogametes, with distinct roles in reproduction.

Conversation

I was reading about the differences between male and female gametes, and it mentioned something called a heterogamete.

Oh really? I’ve never heard that term before. What does it mean?

It refers to gametes that are different in structure, like sperm and eggs.

That’s interesting! So, one is small and motile while the other is larger and nonmotile?

Root Explanation

Heterogamete → It is formed from "hetero-" (from Greek "heteros", meaning different) and "gamete" (from Greek "gametēs", meaning spouse or mate). The word refers to a reproductive cell that is different from another, typically in terms of size or form, such as sperm and egg cells.

Memory Tip

Think of 'different' ('hetero-') reproductive cells ('gamete') — that's why heterogamete refers to cells that are not the same.
