✦ Synopsis

The dynamics of alMe frequencies changing under migration and heterogeneous selection in a subdivided population are investigated. Using perturbation techniques, a stationary state is obtained when migration and selection are both small. Heterogeneous selection leads to a positive correlation between values of F-statistics and heterozygosities when these are compared among sets of subdivided populations. This contrasts with a negative value of the correlation obtained under Wright's classical model of homogeneous selection, and with the absence of correlation in the completely neutral situation.

The purpose of this report is to understand the effects of hybrid zone architecture and genetic drift on cytonuclear genotypic disequilibria. We also study the exact dynamics of the expected values of the cytonuclear genotypic disequilibria for both the homozygotes and heterozygotes in a finite popu

A formula for the effective population size for the finite island model of subdivided populations is derived. The formula indicates that the effective size can be substantially greater than the actual number of individuals in the entire population when the migration rate among subpopulations is smal
