Global DNA methylation of porcine germ cells. a Boxplots representing the median DNA methylation levels (tiles of 100 CpG sites) detected in male (blue) and female (purple) germ cells at the different study time points (D28, D32, D36, D39, and D42). Boxes represent the interquartile range (Q1 to Q3), and whiskers show the minimum and maximum levels of methylation in each case. Methylation levels of pig blastocysts are from [26], mean methylation levels of fetal somatic tissue on D18, D21, and D28 reported by [25] are indicated in orange, and median methylation levels of oocytes and sperm are from [26]. b PCA of DNA methylation of tiles of 100 CpG sites of the samples included in this study
