WebFeb 19, 2024 · Mammalian sperm show a bimodal distribution of hypermethylated and hypomethylated regions, with global methylation levels between 70% and 80% [ 31, 32, 33 ]. DNA methylation is important to prevent retrotransposon activity and genome instability in germ cells [ 34 ]. WebThe methylation of the maternal genome is maintained until the two-cell stage [19,20]. Single-cell epigenome sequencing results show that the median level of sperm methylation undergoes a significant decrease from 80.3% to 38.3% shortly after fertilization. Meanwhile, the maternal genome also shows mild demethylation from 32.4% to 27.8% [21]. gearhart to portland
