Drive/Standard: SR = Sex-ratio drive male, ST = Standard male; male_#: unique numbering for each male; offspring_first_female: number of offspring from mating with first female; offspring_subsequent_females: number of offspring from mating with 10 subsequent females. File 2: female_remating.txt Frequency and timing of female remating in lines from natural populations of Drosophila neotestacea. Pop: population (sea = Washington, kaw = Alberta, ida = Idaho, mon = Montana, pro = Oregon); Line: the line number which individual females were taken from; batch: experiment batch; NMat1: Number of matings by the female on 1 day of mating; TOTIfMatedDay1: total number of times females mated across 2 mating days given they mated on the 1st day; Remated(1yes): Whether females remated on the 2nd day of mating (1=yes, 0=no).
