Fig. 1From: Sperm DNA methylation patterns at discrete CpGs and genes involved in embryonic development are related to bull fertilityThe relationship between bull fertility and sperm DNA methylation profile. (A) Principal component analysis (low-fertility bulls are displayed as green dots, high-fertility bulls as red dots) (B) Dendrogram clustering based on DNA methylation in sperm from all bulls (applied method: Ward method with Euclidean distance; L1 to L10, low-fertility bulls; H1 to H10, high-fertility bulls)Back to article page
