Autocorrelation 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 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 کاملIsolation 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 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 کاملGenetic differentiation and estimation of gene flow from F-statistics under isolation by distance.
I reexamine the use of isolation by distance models as a basis for the estimation of demographic parameters from measures of population subdivision. To that aim, I first provide results for values of F-statistics in one-dimensional models and coalescence times in two-dimensional models, and make more precise earlier results for F-statistics in two-dimensional models and coalescence times in one...
