Fixation index — (FST) is a measure of population differentiation based on genetic polymorphism data, such as Single nucleotide polymorphisms (SNPs) or microsatellites. It is a special case of F statistics, the concept developed in the 1920s by Sewall Wright.This … Wikipedia
Genetic hitchhiking — is the process by which an evolutionarily neutral or in some cases deleterious allele or mutation may spread through the gene pool by virtue of being linked to a beneficial mutation. More generally, genetic hitchhiking can refer to the process by … Wikipedia

Genetic drift — ] Especially in small populations, the statistical effect of sampling error ( during reproduction ) on certain alleles from the overall population may result in an allele ( and the biological traits that it confers ) becoming more common or rare… … Wikipedia
Fixation (population genetics) — In population genetics, fixation occurs when every individual within a population has the same allele at a particular locus. The allele, such as a single point mutation or whole gene, will be initially rare (e.g. originating in one individual),… … Wikipedia
Genetic load — In population genetics, genetic load or genetic burden is a measure of the cost of lost alleles due to selection (selectional load) or mutation (mutational load). It is a value in the range 0 < L < 1, where 0 represents no load. The concept … Wikipedia
Genetic equilibrium — A genetic equilibrium occurs when an allele within a gene pool is not changing in frequency (i.e. evolving). For this to be the case, evolutionary forces acting upon the allele must be equal and opposite. The only basic requirement is that the… … Wikipedia
