P2

Paternity and sperm count data. Variables: Cross - Species identity of first and second male to mate with a D. simulans female, where "s" indicates D. simulans and "m" indicates D. mauritiana, such that "ss" indicates that both males were D. simulans, "ms" indicates that the first male was D. mauritiana and the second male was D. simulans, etc. Treat – time after mating for which paternity and sperm numbers in the female reproductive tract were quantified. ThoraxF - female thorax length, in arbitrary units. ThoraxM1 - thorax length of the first male, in arbitrary units. ThoraxM2 - thorax length of the second male, in arbitrary units. Cop1 – duration in minutes of the first copulation. Cop2 – duration in minutes of the second copulation. Remate – day after first mating (day 0) on which female remated. PriorProg – number of progeny produced by female before remating. P2Prog1 - number of progeny produced after remating sired by the first male. P2Prog2 - number of progeny produced after remating sired by the second male. P2 – proportion of progeny produced after remating sired by the second male. Bursa1 – number of first-male sperm in the bursa. Bursa2 – number of second-male sperm in the bursa. SR1 – number of first-male sperm in the SR. SR2 – number of second-male sperm in the SR. Sp1 – number of first-male sperm in the spermathecae. Sp2 – number of second-male sperm in the spermathecae
