WebSep 20, 2024 · Concretely, GCTA simulates the phenotypes y according to y = Xβ + e, where X is the standardized genotype matrix for the causal variant(s), β is the vector of causal variant effect sizes, and e is a vector of environmental noise terms where each . In other words, the environmental variance is scaled to achieve the desired heritability. WebThe FTO rs8050136 SNP was genotyped using the Illumina (San Diego, CA) GoldenGate chemistry and Sentrix Array Matrix technology on the BeadStation 500GX. Genotype calling was done with the Illumina BeadStudio software and each call was confirmed manually. For quality control purposes, five CEPH control DNA samples (NA10851, …
