title: A new case of human Y chromosome with satellites on the long arm.
abstract: A Y chromosome with satellites at the end of the long arm is reported. The banding techniques RBG, GTC, C and N were used. C-banding revealed a reduction of the heterochromatic part of the chromosome. The pedigree of the family didn't show any pathological feature in the carriers of this morphological variation. The frequency of satellite association was also studied.
