Use of multi-locus genetic data in analyzing gene flow and hybrid zones
We have developed models that considered the effects of gene flow on patterns of nuclear and cytonuclear statistical associations between loci (disequilibria), allowing for estimation of asymmetric migration rates. Such asymmetries arise naturally in plant systems with gene flow from both pollen and seed, and in animal systems with different migration rates in males and females.
