title: Cytological map of human Y chromosome.
abstract: The cytological map of human Y chromosome is investigated at high resolution using Q-banding technique. There was no segmentation of the short arm which is in disagreement with current International Nomenclature. Also, the band q11.22 was not seen in the long arm using different individuals with variable size of Y chromosome. Furthermore, the length variation of nonfluorescent segment is also noted which was not suggested by the nomenclature.
