Mating success decreases in Jhe and clt mutants. Jhe/+ and clt/+ control males successfully mated with 3 females in succession, while experimental Jhe and clt mutant males significantly (Binary Logistic Regression, genotype p < 0.01, trial p < 0.0001, interaction p < 0.0001) decreased their mating success with the 2nd and 3rd females. No. of successful matings/Total no. of pairings for 1st; 2nd; 3rd trials are shown.
