Gene pool

the stock of different genes in an interbreeding population.

Allele frequency

Allele frequency, or gene frequency, is the proportion of a particular allele among all allele copies being considered. It can be formally defined as the percentage of all alleles at a given locus in a population gene pool represented by a particular allele

3 sources of genetic mutation

Gene flow, sexual reproduction mutation

Genetic drift

variation in the relative frequency of different genotypes in a small population, owing to the chance disappearance of particular genes as individuals die or do not reproduce.

Genetic equilibrium

Genetic equilibrium describes the condition of an allele or genotype in a gene pool (such as a population) where the frequency does not change from generation to generation

Speciation

the formation of new and distinct species in the course of evolution

Reproductive isolation

The mechanisms of reproductive isolation or hybridization barriers are a collection of mechanisms, behaviors and physiological processes that prevent the members of two different species that cross or mate from producing offspring, or which ensure that any offspring that may be produced are sterile
