Table 4 Placement of epandrial lobes, mating position and visibility of oviscapt valves in SEM-analysis of D. pachea mating couples
From: Drosophila pachea asymmetric lobes are part of a grasping device and stabilize one-sided mating
Treatment | Total number of mating couples | Number of mating couples with both lobes in ‘wild-type position’ | Number of mating couples with abnormal left lobe position | Number of mating couples with abnormal right lobe position | Number of mating couples with abnormal position of both lobes | Microscale angle of male relative to female (degrees; mean ± SD) | Number of mating couples in which oviscapt valves were visible |
