A No. 15 chromosome with a short arm longer than usual is observed in two phenotypically normal brothers. This chromosome appears to have no visible satellite, shows no N-band staining, and is never involved in satellite association. These results have led us to the conclusion that this chromosome lacks the nucleolus organizer region.

Abstract
A No. 15 chromosome with a short arm longer than usual is observed in two phenotypically normal brothers. This chromosome appears to have no visible satellite, shows no N-band staining, and is never involved in satellite association. These results have led us to the conclusion that this chromosome lacks the nucleolus organizer region.File in questo prodotto:
