In population genetics, the Wahlund effect is a reduction of heterozygosity in a population caused by subpopulation structure. Namely, if two or more subpopulations have different allele frequencies, the overall heterozygosity is reduced, even if the subpopulations themselves are in a Hardy–Weinberg equilibrium. The underlying causes of this population subdivision could be geographic barriers to gene flow followed by genetic drift in the subpopulations. The Wahlund effect was

James Mark Baldwin and others suggested during the eclipse of Darwinism in the late 19th century that an organism's ability to learn new behaviours will affect its reproductive success and will therefore have an effect on the genetic makeup of its species through natural selection. Though this process appears similar to Lamarckism, that view The reasons why a population is split up into several subpopulations can, for example, be geographical barriers that prevent the exchange of genetic material. Then when genetic drift sets in, the choice and effect arises. The Wahlund effect was first recognized in 1928 by the Swedish geneticist Sten Wahlund.

Wahlund-effekt - Wahlund effect Från Wikipedia, den fria encyklopedin I populationsgenetik är Wahlund-effekten en minskning av heterozygositet (det vill säga när en organism har två olika alleler på ett ställe) i en population orsakad av subpopulationsstruktur. To be able to study the evolution and possible effect of drug treatment on ARWMC in large patient samples, it is necessary to have a rating scale constructed for both MRI and CT. We have developed and evaluated a new scale and studied ARWMC in a large number of patients examined with both MRI and CT. 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 .

The book introduced the scientific theory that populations evolve over the of books, and in his final book, he examined earthworms and their effect on soil. Ljudbok Rymd utan stjärnor - författare Jonas Moström - läser Torsten Wahlund.

Simplest qualitative intuition may come from thinking of populations fixed for different alleles (expectation of fixation = frequency of allele in source, starting or founder population). Wahlund effect occurs when genotypic proportions are computed from heterogeneous samples where individuals belonging to genetically differentiated entities are pooled. These entities can represent members of different (and genetically distant) subpopulations, different cohorts, or different cryptic species.

Populations are the fundamental unit of evolution, the smallest object that can evolve differs from p and q of total population , you will see the Wahlund Effect.
