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."

Effect = the result The effect answers the question “ What happened? ” Remember that the effect is the second thing that happens (as a result of the cause, which was the first thing). Sometimes no key words are used. The cause and effect relationship is then suggested or implied by the writer. An effect is what happens as a result of the cause. Of two related events, it’s the one that happens second or last.

In der Populationsgenetik spricht man vom Wahlund-Effekt wenn die Heterozygosität einer Population durch Strukturierung in Unterpopulationen reduziert wird. Insbesondere wenn zwei oder mehr Unterpopulationen unterschiedliche Allelfrequenzen haben, ist die gesamte Heterozygosität reduziert, selbst wenn sich die Unterpopulationen in einem Hardy-Weinberg-Gleichgewicht befinden. Wahlund-vaikutus - Wahlund effect Wikipediasta, ilmaisesta tietosanakirjasta In populaatiogenetiikan , Wahlund vaikutus on vähentää heterotsygoottisuuden (joka on, kun organismi on kaksi eri alleelien kasvupaikalla) on populaation aiheuttama alapopulaation rakenne. 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-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.

In that case, sampling contains a Wahlund effect that affects all statistics all together. 13 Wahlund Effects Inbreeding may be indicated in the parameter \(F\) due to selfing (the most direct type 11 ), mating amongst relatives (the most common type, 12 ), or due to problems that we as the investigator cause due to our ignorance of the underlying demography.

The Wahlund effect is one such way that problems in your study design may incorrectly result in inferences of inbreeding. Here is how it works. Consider two populations, both of which are at Hardy-Weinberg Equilibrium.

However, small populations are endangered not only by the inbreeding effect , but some of its … The Wahlund effect is one such way that problems in your study design may incorrectly result in inferences of inbreeding.

For the Wahlund effect data we set where F was arbitrarily set to 0.5. For each locus in each subsample, the number of genotypes dropped out corresponded to the inferior integer corresponding to d
