Migration — Role in Allele Frequency & Natural Selection
Read this topicExplanations 4
- Entering or Leaving a Population Migration can either increase or decrease genetic diversity. As individuals leave or enter a population, they bring or take away unique alleles.…

- Migration, Alleles, and Gene Flow Genetic migration can either introduce new alleles or remove alleles from a population. Genetic migration is sometimes called gene flow. You ma…

- Migration and Gene Flow One way species combat genetic drift is through the migration of alleles. This is called gene flow. Gene flow is when alleles either enter or exit a popu…
