This article examines how parental education level moderates the genetic and environmental contributions to variation in verbal IQ. Data are from 1909 non-Hispanic Whites and African American sibling pairs from the National Longitudinal Study of Adolescent Health, which obtained nationally-based samples of identical (MZ) twins, fraternal (DZ) twins, full and half siblings, cousins (in the same household), and biologically unrelated siblings. In the whole sample, the variance estimate for… Expand
The moderation of genetic and shared-environmental influences on adolescent drinking by levels of parental drinking.
TLDR
It is found that, at least for male adolescents, genetic influences on drinking appear to be potentiated by exposure to parental drinking. Expand
School Context and Genetic Influences on Aggression in Adolescence
Genetic and environmental contributions to variation in aggression were examined using adolescents' self-reports of aggressive behavior. The National Longitudinal Study of Adolescent Health providedExpand
Does the heritability of cognitive abilities vary as a function of parental education? Evidence from a German twin sample
TLDR
Results for general cognitive ability and nonverbal ability indicated no significant gene x parental education interaction effect, and for verbal ability, a significant nonshared environment (E) x parents education interaction was found in the direction of greater nonsharing environmental influences on verbal abilities among children raised by more educated parents.

Does Parental Education have a Moderating Effect on the Genetic and Environmental Influences of General Cognitive Ability in Early Adulthood?
TLDR
Examination of whether parental education has a moderating effect on genetic and environmental influences of general cognitive ability in early adulthood found a model without moderating effects of parental education on genetic or environmental influences on cognitive scores proved to be the best fitting model.

The moderating role of SES on genetic differences in educational achievement in the Netherlands
TLDR
EA depended on SES both directly and indirectly, and SES moderated the additive genetic and environmental components of EA, and adding information from PGS improved the prediction of children’s EA. Expand
Socioeconomic Status Modifies Heritability of IQ in Young Children
TLDR
Results demonstrate that the proportions of IQ variance attributable to genes and environment vary nonlinearly with SES, and suggest that in impoverished families, 60% of the variance in IQ is accounted for by the shared environment, and the contribution of genes is close to zero; in affluent families, the result is almost exactly the reverse.

A Twin Study of Competence and Behavioral/Emotional Problems Among Adolescents in Taiwan
TLDR
Genetic factors are important for explaining adolescent behavioral problems, especially for girls, while shared environmental influences cannot be ignored for boys, while gender differences in heritability exist for various CBCL-based competence and behavioral/emotional problems. Expand
Developmental Behavioral Genetics and Education
Quantitative behavioral genetics accounts for individual differences in behavior in terms of genetic and environmental sources of variance. Heritability is the proportion of the total variance in aExpand
Environmental Moderators of Genetic Influence on Verbal and Nonverbal Abilities in Early Childhood.
Abstract The study of genotype–environment interaction (G × E) has been dominated by two competing hypotheses, one that heritability is greater in high-risk environments (diathesis-stress) and theExpand

Differences in heritability across groups differing in ability
TLDR
Lower ability subjects show higher heritabilities and lower shared environmentality and this result is attributable to larger differences between DZ twins at low ability levels and to differences between MZ twins, which are either the same across ability level or are smaller atLow ability levels.

Education policy and the heritability of educational attainment
TLDR
Education data on twins and their parents, from the Norwegian twin panel, provide a unique opportunity to determine the impact on the heritability of educational attainment of the more liberal social and educational policies introduced in Norway after the Second World War. Expand

"Family background" frequently has been found to have long-term effects on adult intellectual, occupational, and economic outcomes. Since families differ both genetically and environmentally, it hasExpand
Differences in heritability across groups differing in ability, revisited
TLDR
A sample of 148 identical and 135 fraternal twin pairs from the Western Twin Project who were tested on a battery of intelligence and achievement tests suggest no significant differences in heritability at either the high or the low end, although a trend toward higher heritability for children of higher ability is evident.
