The genetical relationship of impulsiveness and sensation seeking to Eysenck's personality dimensions.
The genetical analysis of covariance structures is used to explore the genetical and environmental intercorrelations of impulsiveness and sensation seeking factors and their conformity to Eysenck's principal personality dimensions. The independent dimensions of psychoticism, extraversion, neuroticism, and lie scale are not found to give a very satisfactory account of the genetical factor structure. In particular, it is clear that impulsiveness and sensation seeking are not simple reflections of extraversion.

Open-field behavior in mice: generality of results from a diallel analysis of replicate selected lines.
Data from a diallel cross of six lines composing a replicated selection study for open-field behavior in mice are reanalyzed to investigate the generality of the findings. The results support the hypothesis that only additive variation would be found for open-field behavior if additional selection lines were derived from the same foundation population.

Mating speed in male Drosophila melanogaster: a psychogenetic analysis.
A diallel analysis of mating speed as measured by the copulation frequency of male Drosophila melanogaster revealed strong directional dominance for high frequency involving a minimum of five genes. The trait as measured is highly correlated with sexual drive and fitness. Consequences for artificial selection and the nature of the heterosis displayed by the crosses are discussed. High copulation frequency of the male is probably the result of unidirectional natuiral selection.
