Regional assignment of a 2.1-kb repetitive sequence to the distal part of the human Y heterochromatin
Abstract
Variants in structure and content of the human Y chromosome were investigated by cytogenetic methods and by restriction endonuclease analysis. It is shown that most or all of the 2.1-kb male-specific reiterated sequence is located in the distal part of the brightly fluorescing heterochromatin.
