The evolution of conspecific gamete precedence and its effect on reinforcement.

摘要: Conspecific gamete precedence, the usage of conspecific sperm by a female that mates with both and heterospecific male, has been found in many taxa. We construct population genetic model to examine evolution precedence its coevolution premating isolation process reinforcement. Our findings suggest can evolve via very similar explore nature selection against hybridization necessary drive this evolution. Moreover, our results confirm prediction Marshall et al. (Trends Ecol. Evol. 2002;17:558-563) will inhibit reinforcement between two species. further find precedence. Both increase reproductive contribute speciation. discuss factors may affect which these phenomena are likely become predominant incipient
