Ejection2

Timing and numbers of first- and second-male sperm ejected after remating, and numbers of first- and second-male sperm remaining in the female reproductive tract after ejection. 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. Remate – day after first mating (day 0) on which female remated. Eject - 1 if female ejected, 0 if she did not eject. EjStart - Minutes after start of mating when female began ejecting a sperm mass (sometimes it got stuck). EjEnd - Minutes after start of mating when female finished ejecting a sperm mass. PriorProg - presence of prior progeny, where 0 = none, 1 = a few, 2 = a lot. Eject1 – number of first-male sperm in ejected sperm mass. Eject2 - number of second-male sperm in ejected sperm mass. ThoraxF - female thorax length, in arbitrary units. ThoraxM - thorax length of the second male, in arbitrary units. 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
