    Notes: Abstract Several twin studies of multiple abilities and educational and socioeconomic variables suggest that a single common factor underlies the contribution of mate selection and cultural inheritance to the covariation of such measures. Theoretical analysis shows that this finding is consistent with a mechanism of mate selection in which specific abilities are merely components of a composite latent variable for which there is assortative mating. We question how far measures of specific abilities reflect behavioral traits of independent adaptive significance.

    Notes: Abstract The transmission of religious affiliation is analyzed in a sample of 3810 Australian twin pairs and their parents. Twins were classified by sex, zygosity, and whether they were living together or apart. Analysis of twin, spousal, and parent-offspring resemblance shows that several different forms of cultural inheritance operate jointly in the transmission of religious affiliation. Model-fitting methods show that (1) the environmental influence of mothers is significantly greater than fathers; (2) there is a substantial amount of assortative mating for religious affiliation; (3) there is a substantial environmental component shared by twins which does not depend on parental religious affiliation; (4) religious affiliation attributed to parents by their children is biased by the religious affiliation of the children; (5) nongenetic effects on the expression of religious affiliation are much greater in twins living together; and (6) a moderate genetic effect on religious affiliation is expressed in females but only when twins live apart. Implications of the method and findings are discussed for other aspects of family resemblance, including the analysis of social and occupational mobility.

    Notes: Abstract The transmission of social attitudes has been investigated as a possible model of cultural inheritance in a sample of 3810 twin pairs from the Australian National Health and Medical Research Twin Registry. Six social attitude factors were identified and univariate genetic models fitted to scores on each factor. A joint multivariate genetic analysis of the six attitude factors, church attendance, and education indicated that the attitudes were correlated—the same genes and shared environments influenced more than one attitude factor. A current controversy regarding social attitudes is whether the significant loadings on this shared environmental component represent true cultural influences or are actually the genetic consequences of phenotypic assortative mating for church attendance and educational attainment (Martinet al., 1986). In our data, church attendance is almost entirely due to the impact of the shared environment. The large shared environmental component on church attendance also accounts for a substantial part of the family resemblance in social attitudes, suggesting that not all of the apparent cultural effects found in earlier studies can be ascribed to the genetic effects of assortative mating. However, church attendance and education do not completely account for the cultural component. Therefore, effects in addition to church attendance, education, and assortative mating for church attendance and education must be involved in the cultural component of the inheritance of attitudes.

    Notes: Abstract The “Virginia 30,000” comprise 29,698 subjects from the extended kinships of 5670 twin pairs. Over 80 unique correlations between relatives can be derived from these kinships, comprised of monozygotic (MZ) and dizygotic (DZ) twins and their spouses, parents, siblings, and children. This paper describes the first application of a fairly general model for family resemblance to data from the Virginia 30,000. The model assesses the contributions of additive and dominant genetic effects in the presence of vertical cultural inheritance, phenotypic assortative mating, shared twin and sibling environments, and within-family environment. The genetic and environmental effects can be dependent on sex. Assortment and cultural inheritance may be based either on the phenotype as measured or on a latent trait of which the measured phenotype is an unreliable index. The model was applied to church attendance data from this study. The results show that the contributions of genes, vertical cultural inheritance, and genotype-environment covariance are all important, but their contributions are significantly heterogeneous over sexes. Phenotypic assortative mating has a major impact on family resemblance in church attendance.
