Does H-Y antigen induce the heterogametic ovary?

abstract：:Transcriptional silencing is a phenomenon in which the transcription of a gene by RNA polymerase II or III is repressed or not, dependent only on the gene's chromosomal location. Two prevailing models exist for silencing: (1) steric hindrance in silenced chromatin inhibits the binding of upstream activator proteins or...
