FAQ
Frequently Asked Questions
No. Migration is the movement of individuals. Gene flow is the transfer of genetic material that results from successful migration and reproduction.
Yes, in some cases. This is called hybridization or introgression, and it can lead to gene flow if the hybrid offspring are fertile and breed back into one of the parent populations.
Genetic isolation, where populations do not exchange genes. This can lead to speciation over time.
It depends. It is generally beneficial as it increases genetic diversity, which helps populations adapt. However, it can be negative if it introduces harmful alleles or disrupts local adaptations.
The transfer of genetic material (alleles) from one population to another.
Gene flow is usually technical/scientific (specialist), academic in register.

Mnemonic
Think of a river FLOWing between two lakes, carrying fish (GENES) from one lake (population) to another.
Conceptual Metaphor
