text: We found that de novo methylation dominated from the late zygote stage to the 4-cell stage because the number of de novo methylated WCG sites was much higher than that of demethylated sites during this developmental period, resulting in an increase in the global methylation level from the late zygote stage to the 4-cell stage (zygote versus 4-cell, P = 1.6 × 10−3).
