Isolation by Distance under Diverse Systems of Mating.
HE effects of restricted dispersion on the genetic properties of a continuous T population have been treated mathematically in a previous paper (WRIGHT 1943a). The conclusions have been applied to the interpretation of observed local variability in a population of a plant, Linanthus Parryi (WRIGHT 1943b) and in one of an animal, Drosophila pseudoobscura (DOBZHANSKY and WRIGHT 1943). The mathema...
متن کاملSpatial distributions of genotypes under isolation by distance.
The spatial distributions of single-locus diploid genotypes, produced within populations of sexually reproducing individuals under isolation by distance, are measured and characterized in detail by quantifying the join-counts for simulated model populations. The models more realistically reflect spatially explicit distributions of genotypes in populations, because unlike the classical theory, t...
متن کاملSpatial structure of two-locus genotypes under isolation by distance.
Extensive Monte Carlo simulations are conducted of spatial distributions of two-locus genotypes in large, continuous populations under isolation by distance models. The results show that substantial patches of double homozygotes are present in the spatial structures, even when loci are unlinked. The stochastic spread of identical two-locus genotypes largely outpowers the tendency for recombinat...
متن کاملAutocorrelation of gene frequencies under isolation by distance.
Spatial autocorrelation statistics are used for description of geographic variation of gene frequencies, but the relationship of these indices with the parameters describing the genetic structure of populations is not established. A simple relation is derived here between kinship coefficient and a measure of spatial autocorrelation, Moran's I. The autocorrelation coefficient of gene frequencies...
متن کاملA stochastic model for reproductive isolation under asymmetrical mating preferences
More and more evidence shows that mating preference is a mechanism that can lead to a reproductive isolation event. In this paper, we consider a haploid population living on two patches linked by migration. Individuals are ecologically and demographically neutral on the space and differ only on a trait, a or A, determining both mating success and migration rate. The special feature of this pape...
