A Wahlund effect typically occurs for organisms for which population subdivision is unknown, if subsamples are collected at larger scales than the actual subdivision unit. In that case, sampling contains a Wahlund effect that affects all statistics all together.

An event that initiates an allele frequency change in an isolated part of the population, which is not typical of the original population, is called the founder effect.

Efecto Wahlund - Wahlund effect De Wikipedia, la enciclopedia libre En genética de poblaciones , el efecto Wahlund es una reducción de la heterocigosidad (es decir, cuando un organismo tiene dos alelos diferentes en un locus) en una población causada por la estructura de la subpoblación.

In population genetics, the Wahlund effect refers to reduction of heterozygosity (that is when an organism has two different alleles at a locus) in a population caused by subpopulation structure. Namely, if two or more subpopulations have different allele frequencies then the overall heterozygosity is reduced, even if the subpopulations themselves are in a Hardy-Weinberg equilibrium. Wahlund effect: Reduction in homozygosity (increase in heterozygosity) when distinct taxa are analyzed jointly, or when they hybridize. Whenever subpopulations vary in gene frequency, the population as a whole will show a Wahlund effect. Null alleles and Wahlund effects are well known causes of heterozygote deficits in empirical population genetics studies as compared to Hardy-Weinberg genotypic expectations. Some authors have theoretically studied the relationship of Wright's F-IS computed from subsamples displaying a Wahlund effect and F-ST before the Wahlund effect, as can occasionally be obtained from populations of long Wahlund effect and Genotype frequency · See more » Hardy–Weinberg principle The Hardy–Weinberg principle, also known as the Hardy–Weinberg equilibrium, model, theorem, or law, states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences. The reasons why a population is split up into several subpopulations can, for example, be geographical barriers that prevent the exchange of genetic material.

Wahlund effect The overall frequency of the alleles of the individual genes does not change in any way when a large population is divided into several smaller populations. However, small populations are endangered not only by the inbreeding effect , but some of its alleles are fixed much more rapidly through genetic drift. A Wahlund effect, the departure from Hardy-Weinberg equilibrium due to mixing of individuals from groups with different allelic frequencies, is the simplest explanation of such deficits. The limited geographic variation of allelic frequencies, however, is grossly inadequate to produce these deficits through a Wahlund effect.
