From: Sexually dimorphic DNA methylation and gene expression patterns in human first trimester placenta
Sample cohorts and quality control. A Summary of the first trimester placenta cohorts and analyses. F = females, M = males. B Principal components analysis for the DNA methylation cohort. The pre-filtered dataset confirms fetal sex. The filtered dataset no longer shows clustering by sex. C Quantile–Quantile plot for the differentially methylated probes (DMP) analysis. Points are individual methylation sites (probes). Red line at Pobserved = Pexpected
