Figure 1From: Intra-specific variation of sperm length in the malaria vector Anopheles gambiae: males with shorter sperm have higher reproductive successIntra-specific variation in sperm length in A. gambiae and A. stephensi males. Experiment 1: there is significant intra-specific variation in sperm length among males in both A. gambiae and A. stephensi. The mean sperm length in testis A is strongly correlated with that in testis B in males of A. gambiae (n = 25 males) and A. stephensi (n = 17 males).Back to article page
