Table 2. Proportion of the genetic variance explained by chromosome (joint) and the whole genome (combined) using 8,901 EA and 2,860 AA individuals.
The trait analyzed is first-visit SBP and DBP and long-term average (LTA) SBP and DBP respectively using genotyped and imputed SNPs. The heritability (h2), its standard error (se) and significance value (P) are shown.
