h2SNP is the heritability due to additive influences estimated from genotyped SNPs. “Unrelated” refers to a subsample based on filtering the genetic relatedness matrix (GRM) with a threshold of 0.05 to select unrelated pairs of subjects. Ns are 1678 for theta measures and 2040 for delta measures. h2SNP in the whole sample is based on the method of Zaitlen et al. (2013) to estimate the SNP heritability in samples of related individuals. h2unexplained reflects the portion of heritability captured by phenotypic relationships that is not due to genotyped SNPs, analogous to ‘missing heritability.’ The sum of the two (h2total) provides an estimate of narrow-sense heritability.
