Weighted gene co-expression network analysis (WGCNA)
(A) WGCNA DNA methylation module and developmental stage relationships. Modules with different colors are correlated with stages PGC, prospermatogonia, spermatozoa, pachytene spermatocytes, round spermatids, caput spermatozoa, and cauda sperm. The colored correlation coefficient reflects the modules with the correlation coefficient number and statistical p value in brackets for each module stage comparison.
(B) The number of DNA methylation sites in each module is listed under each module color.
