Fig. 7: Standardised variance components for educational attainment in the offspring generation.

From: Understanding indirect assortative mating and its intergenerational consequences for educational attainment

Fig. 7

Estimated with the full iAM-COTS model applied to 212,070 extended families. Data are presented as variance components with 95% confidence intervals, where the total variance is the sum of all components. The variance components are additive genetic factors (\({{{\rm{V}}}}_{{{\rm{A}}}}\), red), variance attributable to gene-environment correlations (\({{{\rm{V}}}}_{{{\rm{rAC}}}}\), brown), sibling-shared environmental factors (\({{{\rm{V}}}}_{{{\rm{C}}}}\), blue), and non-shared environmental factors (\({{{\rm{V}}}}_{{{\rm{E}}}}\), yellow). Patterned areas of the bars indicate variance associated with parents’ educational attainment. Source data are provided as a Source Data file and at https://osf.io/dznbk/.
