Summary
The I.Q. scores of 3558 individuals from a pedigree study were subjected to a biometrical genetical analysis. Only models which took account of assortative mating provided a statistically adequate summary of the observed variation for intelligence. The conclusions of this study agreed with a published analysis of other data in demonstrating a large additive genetical component of variation and the effect of assortative mating. Although the study detected no significant dominance, it was shown on theoretical grounds that the observed data were consistent with complete dominance for I.Q.
