  1. Gene pool: collection of alleles in all of thr individuals of a population.

  1. Allele Frequency: the proportion of one allele, compared with all alleles for that trait, in the gene pool.

  1. Mutation: a change in the DNA sequence of an organism.

  1. Recombination: the process where pueces of DNA are exchanged between chromosomes.

  2. Hybridization: breeding two different organisms usually from distinct species ir genetuc lineages.

  3. Gene flow: movement of alleles from one population to another.

  4. Genetic drift: the change in frequency of an existing gene variant in the population due to random change.

  5. Bottleneck effect: genetic drift that results from an event that drastically reduces the size of a population.

  6. Founders effect: genetic drift that occurs after a small number of individuals colonize a new area.

  7. Reproductive isolation: final stage in speciation, in which members of isolated populations are no longer able to reproduce.

  8. Speciation: evolution of two or more species from one ancestral species.
