Abstract:
In a recent issue, Rausch and Morgan (2005) analyzed the role of selfing in the autopolyploidization process theoretically based on the formulation of Felber (1991), although they did not explicitly model a pollen pool. This paper reformulates the male contribution to outcrossing in terms of gamete frequencies within a pollen pool. This is a general issue when considering competition between sexual and selfing or asexual forms in a single population, which must be considered in theoretical treatments.
