Fig. 4: Standardised variance components for educational attainment.

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

Fig. 4

From the iAM-ACE model (a, b) and the parent generation in the iAM-COTS model (c, d), for observed educational attainment (i.e., the focal phenotype, a and c) and the associated sorting factor (b, d) in 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), sibling-shared environmental factors (\({{{\rm{V}}}}_{{{\rm{C}}}}\), blue), twin-shared environmental factors (\({{{\rm{V}}}}_{{{\rm{T}}}}\), purple), non-shared environmental factors (\({{{\rm{V}}}}_{{{\rm{E}}}}\), purple), and variance attributable to gene-environment correlations (\({{{\rm{V}}}}_{{{\rm{rAC}}}}\), brown). Source data are provided as a Source Data file and at https://osf.io/dznbk/.
