Figure 3:
Methylation levels of the genes located within the sperm PMDs. (a) Dot plot of the methylation levels of the genes located in the sperm PMDs. Only gene methylation level with standard deviations less than 20% among somatic tissues or sperm cells were used for plotting. (b) CpG methylation status of the partial PMD (chr23:30,700,001–31,700,000) clustered genes related to histones. Sperm1 A and B: sperm samples from Holstein 1; Sperm2 A and B: sperm samples from Holstein 2; WBC: whole blood cells; MAM: mammary glands; CORTEX: prefrontal cortex of the brain.
