In the following, we will only consider mouse body weight as sample trait. The module eigengenes of the following three modules were highly correlated with body weight: brown (409 genes, correlation with weight r = 0.59, correlation p-value p = 5 × 10-14), red (221 genes, r = 0.51, p = 3 × 10-10), and salmon (91 genes, r = 0.43, p = 2 × 10-7).
