Genome-wide association studies on human behavioural traits are producing large amounts
of polygenic signals with significant predictive power and potentially useful biological clues …

Meta-analyses of genome-wide association studies, which dominate genetic discovery, are
based on data from diverse historical time periods and populations. Genetic scores derived …

Behavior genetics studies how genetic differences among people contribute to differences in
their psychology and behavior. Here, I describe how the conclusions and methods of …

A recent series of papers in Nature Genetics described several combined Genome Wide
Association Studies (GWAS) of height. Although height is a highly heritable trait that can be …

Objectives. We explain why traits of interest to behavioral scientists may have a genetic
architecture featuring hundreds or thousands of loci with tiny individual effects rather than a …

A recent genome-wide-association study of educational attainment identified three single-
nucleotide polymorphisms (SNPs) whose associations, despite their small effect sizes (each …

The field of human behavioral genetics has come full circle. It began by using twin/family
studies to estimate the relative importance of genetic and environmental influences. As large …

Genetic correlations estimated from genome-wide association studies (GWASs) reveal
pervasive pleiotropy across a wide variety of phenotypes. We introduce genomic structural …

Basic quantitative genetic models of human behavioral variation have made clear that
individual differences in behavior cannot be understood without acknowledging the …

While volunteer-based studies such as the UK Biobank have become the cornerstone of
genetic epidemiology, the participating individuals are rarely representative of their target …
