  • P2+ is the fraction of offspring sired by the wild-type B3-09 males when they are the second to mate, and P2bw′ is the fraction of offspring sired by the bwD males when they are the second to mate. Fec+ and Fecbw are the fecundities of doubly-mated females in experiments 1 and 2, respectively, and ΔFec+ and ΔFecbw are the proportion increase in fecundity of doubly mated over singly-mated females. Fracdoub is the fraction of females that mated both males pooled over both experiments.
