Between Quote by Peter R. Grant
“Exchange of breeding individuals between two populations tends to homogenize their gene pools.”
About This Quote
Gene flow through individual exchange reduces genetic differences between groups, making their gene pools more similar.
In simple terms: Migration mixes genetic material across populations.
Key Takeaway
Movement of individuals equalizes genetic variation.

Questions to Reflect On
- How does gene flow balance with local adaptation?
- When might restricting movement be beneficial?
A Different Perspective
Excessive gene flow can erode local adaptations, reducing fitness in specific environments.
