• Resumen

  • In our recent article in TREE [ 1 ], we suggested that the cost of mating with a heterospecific, and thus the strength of selection against hybridization acting upon the individual, is reduced for those individuals that mate multiply and with at least one conspecific relative to individuals that mate once and with a heterospecific. Given the above and assuming that, in multiple mating systems, individuals always mate with at least one conspecific, we inferred that reinforcement would be less likely to occur in promiscuous systems than in monogamous systems. Under this scenario, our inferences about the role of multiple mating, per se, are correct.
