(last updated on 2023/12/19)Abstract:
Population structure has genome-wide effects on the maintenance of neutral genetic diversity. Here, the level of genomic diversity is explored across a range of reproductive systems, including full gonochorism, full hermaphroditism, androdioecy, and gynodioecy. While the presence of gonochores (males or females) can reduce inbreeding, the partitioning of reproductives into mating types can reduce effective population number. Further, sex-specific viability directly affects the relative numbers of the mating types and can influence sex ratio evolution. A ratio of effective numbers provides an index for gauging the effects on genomic diversity of effective number, sex-specific viability differences, and the evolving quantitative trait of the evolutionarily-stable population sex ratio is compared across a range of monoecious and dioecious systems of reproduction.
