WebMay 31, 2024 · The founder effect is the reduction in genetic variation that results when a small subset of a large population is used to establish a new colony. The new population may be very different from the original population, both in terms of its genotypes and phenotypes. What increases heterozygosity? WebAug 18, 2024 · In line with strong and significant heterozygosity deficiencies across loci, likely explained by Wahlund effect, high genetic structure was observed among the three seas (ENA corrected F ST = 0. ...

WebMay 11, 2024 · Three published papers in this journal have considered the proposition that, under a Wahlund effect caused by population mixture, a positive correlation is expected between single-locus values of FIS for a sample from the mixture and FST between the populations contributing to the mixture. 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
