Definition

The process where genes from one species mix into the gene pool of another species, often through repeated breeding with one of its parent species.

Example

Introgression can lead to new traits in a population as genes from different species combine.

Conversation

I was reading about introgression in plants the other day.

Oh really? What is it exactly?

It's when genes from one species mix into another, usually through hybridization.

That sounds fascinating! I didn't know plants could share genes like that.

Root Explanation

Introgression is formed from "intro-" (meaning inward) and "gressio" (from "gradi", meaning to step or go). The term describes the process of genes moving inward from one species into the gene pool of another through hybridization.

Memory Tip

Think of 'going inward' ('intro-') and 'stepping' ('gressio') into another species' gene pool — that's what introgression means.
