WebThis reduction in heterozygosity is known as the Wahlund effect (Wahlund, 1928). In practice, departures from Hardy–Weinberg proportions due to non-random mating and population structure tend to be genome-wide (i.e., their effects can be seen at multiple loci). View chapter Purchase book. WebThe Wahlund effect for two loci has been worked out. It is shown that the double homozygotes will be in an apparent excess, just as in the one-locus case. 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. Details

WebIn this study we implemented a system of trapping, consisting of a central trap and two to four satellite traps around the central one to evaluate a possible role of the Wahlund effect in tsetse flies from three Cameroon human and animal African trypanosomiases foci (Campo, Bipindi and Fontem). WebWhat the Wahlund effect does. If you sample from subpopulations that have diverged sufficiently, you will observe an overall deficiency of heterozygotes .

WebPOPULATION GENETICS: Subdivided populations and the Wahlund Effect. A river changed course 20 years ago, so that it now lies exactly in the middle of a habitat. Compare heterozygosities determine whether the population is subdivided. Is there evidence of subdivision? This problem has been solved! WebOrtiz et al. indicated that the loss of heterozygotes and subsequent Hardy-Weinberg disequilibrium in subpopulations might be due to the Wahlund effect . This effect could be compatible with the geographical isolation of several flocks included in this study, confirmed by Admixture and Netview analysis. WebNov 25, 2014 · Another potential explanation for the departures from Hardy-Weinberg equilibrium is the Wahlund effect [101].
