mxs

Numbers of sperm transferred and stored for D. mauritiana females mating with D. simulans males. Variables: Cross - mxs = D. mauritiana female mating once with a D. simulans male; mxsm = D. mauritiana female mating first with a D. simulans male followed by a D. mauritiana male; mxms = D. mauritiana female mating first with a D. mauritiana male followed by a D. simulans male. Cop - copulation duration in minutes, for second copulation for mxsm and mxms crosses. 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

本数据集记录了毛里求斯果蝇（D. mauritiana）雌虫与拟果蝇（D. simulans）雄虫交配时的精子转移与储存数量。变量说明如下：
Cross：
mxs：毛里求斯果蝇雌虫仅与拟果蝇雄虫单次交配；
mxsm：毛里求斯果蝇雌虫先与拟果蝇雄虫交配，随后再与毛里求斯果蝇雄虫交配；
mxms：毛里求斯果蝇雌虫先与毛里求斯果蝇雄虫交配，随后再与拟果蝇雄虫交配。
Cop：指mxsm与mxms交配组合中第二次交配的时长，单位为分钟；
Bursa1：交配囊内第一头雄虫的精子数量；
Bursa2：交配囊内第二头雄虫的精子数量；
SR1：储精囊（SR）内第一头雄虫的精子数量；
SR2：储精囊（SR）内第二头雄虫的精子数量；
Sp1：受精囊内第一头雄虫的精子数量；
Sp2：受精囊内第二头雄虫的精子数量。
