We provide particular focus on the evolution of genomic elements that confer the unique epigenetic features that characterize the inactive X chromosome. Keywords: X chromosome, XCI, imprinting, noncoding RNA, … That imprinting might be a feature of mammalian development was suggested in breeding experiments in mice carrying reciprocal chromosomal translocations. Nucleus transplantation experiments in mouse zygotes in the early 1980s confirmed that normal development requires the contribution of both the maternal and paternal genomes.
