E ⁡ ( f ( A a ) ) = 2 p q , {\displaystyle \operatorname {E} (f (\mathbf {Aa} ))=2pq,\!} where p and q are the allele frequencies of A and a, respectively. It is also the probability that at any locus, two alleles from a random individual of the population are identical by descent .

104 30 Equation Research & Development HB. 0858771600 Leif Wahlund. 042240240. Box 9026. 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 first the ratio of the excess homozygosity due to the Wahlund effect (which equals twice the variance in the pi, given by Var p), relative to the expected overall expected heterozygosity for the whole set of populations, given by 2 (which can also be viewed as twice the variance of a binomial variable, which is x (1 - x) or pq), as noted below.

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 ratio of the excess homozygosity due to the Wahlund effect (which equals twice the variance in the pi, given by Var p), relative to the expected overall expected heterozygosity for the whole set of populations, given by 2 (which can also be viewed as twice the variance of a binomial variable, which is x (1 - x) or pq), as noted below. 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.

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. The mathematics of PDEs and the wave equation Michael P. Lamoureux ∗ University of Calgary Seismic Imaging Summer School August 7–11, 2006, Calgary Abstract Abstract: We look at the mathematical theory of partial diﬀerential equations as applied to the wave equation. In particular, we examine questions about existence and En biologie des populations, l'effet Wahlund est un excès d'homozygotes (ou un déficit en hétérozygotes) par rapport à l'équilibre de Hardy-Weinberg qui traduit la subdivision de la population étudiée en plusieurs populations qui n'échangent pas ou peu de gamètes.

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 . 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.

The Hardy-Weinberg Theorem holds under "more realistic" conditions: (1) multiple alleles/ locus. p+ q + r = 1. (p+ q + r)2 = p2+ 2pq + q2+ 2qr + r2+ 2pr = 1.
