Descriptive statistics for the sex ratios (proportion male) and clutch sizes of Nasonia vitripennis lines C222A (L) and HV06 (H) From Pannebakker et al. (2008) and for the recombinant male genotypes from the cross C222A × HV06 when backcrossed into both the H and L backgrounds. Data are presented as means (standard error).
