Figure 3. — Correlation between gametocyte density, representation in the gametocyte pool and mosquito infections. The density of gametocytes (gcts) for avirulent (grey circles, CW_avir) and virulent (black circles, CW_vir) parasites in mixed genotype infections with common competitor, DK, correlates positively with representation in the gametocyte pool and in mosquitoes. (a) For a given gametocyte density, CW_vir (r² = 0.31, p = 0.02) gains greater representation in the gametocyte pool than CW_avir (r² = 0.39, p < 0.001). (b) The proportion of CW gametocytes correlates positively with the frequency of the CW allele within infected mosquitoes (r² = 0.85, p < 0.001; for both genotypes). Put simply, because CW_vir achieves greater representation than CW_avir in the gametocyte pool, it gains greater representation in infected mosquitoes. Data are presented for all treatment groups ((a) experiment 4 and experiment 3 on days of mosquito feeds only, N_vir = 127, N_avir = 132; (b) experiment 4 N_vir = 18, N_avir = 21).
