Mammalian X and Y chromosomes evolved from an autosomal pair; the X retained and the Y gradually lost most ancestral genes. In females, one X chromosome is silenced by X inactivation, a process that is often assumed to have evolved on a broadly regional or chromosomal basis. Here we propose that genes or clusters common to both the X and Y chromosomes (X-Y(More)
The human ZFX, human ZFY, and mouse Zfx genes have CpG islands near their 5; ends. These islands are typical in that they span about 1.5 kb, contain transcription initiation sites, and encompass some 5' untranslated exons and introns. However, comparitive nucleotide sequencing of these human and mouse islands provided evidence of evolutionary conservation(More)
