title: Origin and structure of a satellited Y chromosome.
abstract: A chromosome Yqs was detected in a normal male. The origin and structure of this chromosome was investigated by means of different techniques: CBG, Ag-NOR, QFQ, THA, DA/DAPI and Distamycin A. The conclusion was reached that the Yqs chromosome was actually a Yq/15p translocation, where the Y chromosome had lost completely the Yq12 band. These findings suggested that the absence of the heterochromatic portion of the Y chromosome does not determine infertility.
