Document Summary
A note on optimal mate selection by plants summary. Number of male preferred offspring different than the number of female-preferred offspring for that one male. This leads to different pollen acceptance, monecy, and dioecy. Concerned with expected differences between the sexes in optimal parentage mixtures, and how a plant might produce these differences. If seed productive potential is equal, should be no preference for which female is selected. A females fitness not optimized by having all possible males sire seeds, but some optimal number of them because: Males may not be the best genotypes to have the higher fitness. A desired amount of heterogeneity in the area is required (less inbreeding depression in future generations) The cost of getting more pollen may be greater than the benefit of getting more different male pollen. A female"s fitness may depend on how many males/females sired.
