Data from three experiments bearing on the relative stability of the four mating systems required to test the restrictions against inbreeding and unequal family size were examined in relation to the results given by Robinson & Bray (1965). Tribolium castaneum was the experimental animal used in these experiments.

An analysis of variance indicated that both restrictions were probably effective (P approximately 0·10) in reducing the phenotypic variability of control population means. It seems likely that the apparent gain in stability obtained when the inbreeding restriction was used in addition to the restriction against unequal numbers is due to non-random genotypic proportions which would affect estimates of genetic variability based on assumptions of random mating.
