The influence of origin of mating partners on number and sex ratio of F1-offspring in the parasitoid wasp Nasonia vitripennis. A F1-female offspring; B F1-male offspring; C F1-total offspring; D sex ratio. Mating partners originated from the same or from different microsatellite clusters (with k = 3 or k = 5 subpopulations), or from the same or different microhabitats. Box and whisker plots show minimum, maximum, 1st and 3rd quartile, and median. Levels of significance are based on generalized linear models, family “negative binomial”, followed by Tukey-test. For test statistics see Table 5
