Results of Regression Analyses Predicting Children’s Development and Academic Performance From Mother’s and Children’s Polygenic Score (PGS)

Outcome	Child development (n = 1,611, r2 = .044)		Child academic performance (n = 1,267, r2 = .056)
	Mother PGS	Child PGS	Mother PGS	Child PGS
Standardized	0.114 [0.058, 0.171]	0.058 [0.002, 0.113]	0.087 [0.020, 0.154]	0.083 [0.016, 0.150]
Percentile ranked	0.034 [0.017, 0.050]	0.017 [0.001, 0.033]	0.030 [0.011, 0.049]	0.025 [0.006, 0.044]

Note: Standardized coefficients are shown, with robust 95% confidence intervals in brackets. The ns are for mother–child dyads. Child development was indexed by scores on the Early Years Foundation Stage Profile; child academic performance was indexed by scores on the Key Stage 1.
