The Wahlund effect assumes that the overall population is panmictic.. In genetics, random mating involves the mating of When a population is in Hardy-Weinberg equilibrium, it is not evolving.

If you know of any terms that have been omitted from this glossary that you feel would be useful to include, 2021-03-24 An effect is what happens as a result of the cause. Of two related events, it’s the one that happens second or last. To determine the effect, ask the question “What happened?" What is an "EFFECT"? 4.

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.

If you sample from subpopulations that have diverged sufficiently, you will observe an overall deficiency of heterozygotes . 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). The Wahlund Effect and F Statistics -- The Interaction of Drift and Gene Flow The distribution of genetic variation within and between demes is primarily due to the balance between gene flow and drift. We can measure this balance by a set of "F statistics." This yields yet another interpretation of the phrase "inbreeding coefficient." Wahlund effect. In large populations which contain sub-populations there are fewer homozygotes than in the average for the set of subdivided populations.

Whether the heterzygotes are in deficiency or excess depends on the sign of the covariance of gametes between populations. Gamete disequilibrium is also dependent upon the covariance.
