Note: The ratios are BY265G:N67 or NSM; No. mos, number of mosquitoes dissected; No. FO, number of fluorescent oocysts; No. NFO, number of non-fluorescent oocysts; RFO, ratio of fluorescent oocysts over non-fluorescent oocysts; SD, standard deviation; the relatively large standard deviations were likely due to the differences in the amount of blood taken by individual mosquitoes. *, P<0.01 compared with the ratios from 1:1 crosses (unpaired t-test), and #, P<0.01 compared with ratios of 10:1 crosses (unpaired t-test). Mosquitoes were dissected on day 7 after feeding infected mice.
