Genetic incompatibility drives mate choice in a parasitic wasp

Table 1 Numbers of eggs produced, haploid male (HM), diploid male (DM), female (F), undetermined male (UM) offspring, and the probability that a matched mating by chance did not result in diploid male production (matching probability, calculated as 0.5 ^{(n diploid offspring)} )

Matings are considered matched if DM were produced and in all replicates of the control group (see above). Wasps 1 and 17 were omitted from statistical comparison of matched matings (Fisher test), since the matching probability > 0.05 did not allow for unambiguous classification. Including these data points either as matched or unmatched does not change the conclusions from the Fisher test.
