Screening for differentially expressed genes regulating sheep tail fat deposition using multiple methods. (A) DEGs regulating tail fat deposition in sheep; red represents upregulation, blue represents downregulation. (B) Soft threshold power versus scale-free topological model fit index and average connectivity, with 9 selected as the appropriate soft power. (C) Gene clustering based on dissimilarity metrics. (D) Clustering of samples and indicator traits. (E) Association analysis between gene modules and different traits, the blue module is the most specific module for the fat-tail trait. (F) Venn plot showing the intersection of DEGs with blue module genes
