Maintenance of genetic variation in apomictic plant populations. I. Single locus models

Summary Populations undergoing selfing, outcrossing and apomixis were studied. Genotypic transition equations were established which allow the properties of equilibrium populations to be discussed. Particular attention was paid to the continued maintenance of heterozygosity. It was found that apomix...

Description
Summary:Summary Populations undergoing selfing, outcrossing and apomixis were studied. Genotypic transition equations were established which allow the properties of equilibrium populations to be discussed. Particular attention was paid to the continued maintenance of heterozygosity. It was found that apomixis has no effect on the maintenance of polymorphism in species which otherwise out-cross, but in species which partially or completely self, the possibility of the selective maintenance of balanced polymorphism was enhanced.
