Gene frequency. The percentage of a given allele in a population of organisms. See Allele.
Gene insertion. The addition of one or more copies of a normal gene into a defective chromosome.

"The major tenets of the evolutionary synthesis, then, were that populations contain genetic variation that arises by random (ie. not adaptively directed) mutation and recombination; that populations evolve by changes in gene frequency brought about ...

Genetic drift describes changes in gene frequency that cannot be ascribed to selective pressures, but are due instead to events that are unrelated to inherited traits.

Studies in Sardinia and Papua New Guinea have found that the gene frequency of β-thalassaemias is related to the level of endemicity in a given population.

founder effect Changes in gene frequency that occur when a few individuals from a parental population colonize new habitats; the change is a result of founding individuals not having a representative sample of the parental population's genes.

This outcome is similar to the operation of genetic drift in neutral alleles of nuclear genes: in due course a given allele reaches a gene frequency of 100% or disappears entirely [Link to discussion].
