  • Gene Flow
    Movement of individuals or gametes between populations, altering allele frequencies and promoting evolutionary change.
  • Allele Frequency
    Proportion of a specific genetic variant within a population, which can shift due to migration events.
  • Population
    Group of interbreeding organisms sharing a gene pool, potentially affected by incoming or outgoing genetic material.
  • Genetic Variation
    Diversity of genetic traits within or between populations, often reduced as groups exchange alleles.
  • Evolution
    Process of change in genetic composition of populations over time, influenced by migration of alleles.
  • Gamete
    Reproductive cell capable of transferring genetic material between populations, facilitating gene exchange.
  • Natural Selection
    Mechanism favoring certain alleles, which can be spread to new populations through migration.
  • Genetic Drift
    Random fluctuation in allele frequencies, sometimes counteracted by the introduction of lost alleles via migration.
  • Barrier
    Physical or environmental obstacle separating populations, which can be overcome by movement of individuals.
  • Genetic Diversity
    Range of genetic differences within a population, potentially increased by introduction of new alleles.
  • Migration
    Movement of organisms from one population to another, resulting in gene exchange and altered genetic makeup.
  • Lost Allele
    Genetic variant previously absent from a population, which can be reintroduced through movement of individuals.
  • Mechanism of Evolution
    Process such as gene flow that drives changes in genetic composition across generations.
  • Similarity
    Degree to which populations become alike genetically, often increased by exchange of alleles.
  • New Allele
    Genetic variant not previously present in a population, which can be introduced through migration.
