Estimation of migration rates and population sizes in geographically structured populations
نویسنده
چکیده
The estimation of population parameters from genetic data can help reveal past migration patterns or past population sizes. The transformation from raw genetic data to population parameters needs a model, which should reflect the true relationships between subpopulations. Often the models are overly simplified and do not allow, for example, for differences in population sizes and differences in migration rates. I stress here the point that it is important to consider possible asymmetries in migration rates and differences in population sizes. Very recently several estimators based on the direct use of allele frequencies and based on coalescence theory have been developed. All these outperform migration rate estimators based on FST.

Effect of unsampled populations on the estimation of population sizes and migration rates between sampled populations.
Current estimators of gene flow come in two methods; those that estimate parameters assuming that the populations investigated are a small random sample of a large number of populations and those that assume that all populations were sampled. Maximum likelihood or Bayesian approaches that estimate the migration rates and population sizes directly using coalescent theory can easily accommodate d...
متن کاملInferring human population sizes, divergence times and rates of gene flow from mitochondrial, X and Y chromosome resequencing data.
We estimate parameters of a general isolation-with-migration model using resequence data from mitochondrial DNA (mtDNA), the Y chromosome, and two loci on the X chromosome in samples of 25-50 individuals from each of 10 human populations. Application of a coalescent-based Markov chain Monte Carlo technique allows simultaneous inference of divergence times, rates of gene flow, as well as changes...
متن کاملEffective sizes for subdivided populations.
Many derivations of effective population sizes have been suggested in the literature; however, few account for the breeding structure and none can readily be expanded to subdivided populations. Breeding structures influence gene correlations through their effects on the number of breeding individuals of each sex, the mean number of progeny per female, and the variance in the number of progeny p...
متن کاملMaximum-likelihood estimation of migration rates and effective population numbers in two populations using a coalescent approach.
A new method for the estimation of migration rates and effective population sizes is described. It uses a maximum-likelihood framework based on coalescence theory. The parameters are estimated by Metropolis-Hastings importance sampling. In a two-population model this method estimates four parameters: the effective population size and the immigration rate for each population relative to the muta...
متن کاملUsing temporally spaced sequences to simultaneously estimate migration rates, mutation rate and population sizes in measurably evolving populations.
We present a Bayesian statistical inference approach for simultaneously estimating mutation rate, population sizes, and migration rates in an island-structured population, using temporal and spatial sequence data. Markov chain Monte Carlo is used to collect samples from the posterior probability distribution. We demonstrate that this chain implementation successfully reaches equilibrium and rec...
