Test statistics of experiments on sexual isolation among females and males from different strains in Nasonia vitripennis

Response variable	Factors	Chi2	df	p
Occurrence of copulation	Ms-cluster (k = 3)	0.1269	1	0.722
	Ms-cluster (k = 5)	3.7351	1	0.053
	Microhabitat	1.1870	1	0.276

ANOVA test statistics based on a generalized linear model, family “binomial”, with the occurrence of copulations as response variable and the affiliation to the same or different microsatellite clusters (either based on k = 3 or k = 5 populations) and the microhabitat of wasps (same microhabitat, different microhabitats) as factors
