140-144. It is suggested that Wahlund effect cannot be an important factor of deviations from Hardy-Weinberg proportions in natural populations in the majority of instances, but it can have a substantial contribution to heterozygote deficiency in a population that has low genetic diversity compared to that among immigrants or in mixed samples that contain comparable fractions of individuals from In physics, Washburn's equation describes capillary flow in a bundle of parallel cylindrical tubes; it is extended with some issues also to imbibition into porous materials. The equation is named after Edward Wight Washburn; also known as Lucas–Washburn equation, considering that Richard Lucas wrote a similar paper three years earlier, or the Bell-Cameron-Lucas-Washburn equation, considering J.M. Bell and F.K. Cameron's discovery of the form of the equation in 1906. Efect Wahlund - Wahlund effect De la Wikipedia, enciclopedia liberă În genetica populației , efectul Wahlund este o reducere a heterozigozității (adică atunci când un organism are două alele diferite la un locus) într-o populație cauzată de structura subpopulației.

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.

Equation 6.10 shows that the Fst defined in terms of probability of identity by descent can be related to the amount of gene flow, m, under the island model of gene flow in an equilibrium population. In the island model, a species is subdivided into a large number of local demes of equal size and with each local deme receiving a fraction m of its genes per generation from the species at large

In the island model, a species is subdivided into a large number of local demes of equal size and with each local deme receiving a fraction m of its genes per generation from the species at large 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. Lets see. The observed allele frequencies from the 200 individuals are: \[\begin{aligned}p_A & = \frac{2*65 + 90}{400} \\& = 0.55 \\p_B & = \frac{2*45 + 90}{400} \\ & = 0.45\end{aligned}\] which would result in expectations under HWE for genotypes to be: The Wahlund effect can be extended at multipl e loci where it leads to an apparent excess of double homo zygotes and either an excess or a defi cit of heterozygote 2013-11-15 · The Wahlund effect is both the apparent excess of homozygotes and the deficit of heterozygotes observed at single locus data in a large ‘sample’ of individuals due to the existence of population subdivision.
