Sex Differences in Early Embryogenesis: Inter‐Chromosomal Regulation Sets the Stage for Sex‐Biased Gene Networks
25 Jun 2018
Abstract excerpt
Sex-specific transcriptional and epigenomic profiles are detectable in the embryo very soon after fertilization. I propose that in male (XY) and female (XX) pre-implantation embryos sex chromosomes establish sexually dimorphic interactions with the autosomes, before overt differences become apparent and long before gonadogenesis. Lineage determination restricts expression biases between the sexes, but the...
