Extended Data Fig. 7: GCTA-GREML power estimates.

GCTA-GREML (genome wide complex trait analysis – genomic-relatedness-based restricted maximum-likelihood) genetic (co)variation power estimates. The plot on the left illustrates the relationship between the power (y-axis) to accurately quantify narrow sense heritability (x-axis) for varying sampling sizes (from 300 to 2100). The plot on the right illustrates the same relationship but for presence/absence microbial traits, where the number of presence and absence individuals is balanced.
