Time to copulation was measured in matings within and between two inbred Drosophila melanogaster strains, Edinburgh (E) and 6C/L, using groups of one or five flies of each sex. The E males, which mated faster, usually mate with E females, which are less likely to be fertilized and have fewer progeny whose adult viability is lower. Although generally E males mated far faster with E females than did 6C/L males, there was no difference between the males when with 6C/L females. This need not imply any mating discrimination by E females, but only differences between the strains in the use of preening as a general repulsion movement toward other flies. It is suggested that a greater variety of behavioral and other characteristics (the "behavioral phenotype") should be considered in studies of mating speed and assortative mating, especially where mating speed is being considered as a major component of fitness.
在两个近交系黑腹果蝇品系，即爱丁堡（E）品系和6C/L品系内以及品系间的交配中，使用每组一雄一雌或一雄五雌的果蝇组合来测量交配时间。交配速度较快的E品系雄蝇通常与E品系雌蝇交配，而E品系雌蝇受精的可能性较小，其后代数量较少，且成年后的存活率较低。虽然一般来说，E品系雄蝇与E品系雌蝇交配的速度远比6C/L品系雄蝇快，但当与6C/L品系雌蝇交配时，两种雄蝇之间没有差异。这不一定意味着E品系雌蝇存在任何交配歧视，而仅仅是品系间在将梳理作为对其他果蝇的一般排斥行为上存在差异。有人建议，在研究交配速度和选型交配时，尤其是将交配速度视为适合度的主要组成部分时，应考虑更多样化的行为和其他特征（“行为表型”）。
