The correlation between sperm length and reproductive success in A. gambiae males. Experiment 3: The proportion of inseminated females (insemination success; a), the proportion of females with at least one motile sperm in their spermathecae (sperm motility; b) and the proportion of ovipositing females (oviposition success; c) decrease with the sire family's mean sperm length in A. gambiae. The sizes of the circles represent the number of females in the denominator of the proportion. The lines of best fit are shown for the 16 sire families.
