Accurate identification of the human Y chromosome
Clinical Genetics, 1974Examination by light microscopy of cells of various constitutions with one Y, two Ys, or no Y was made by six experienced cytogeneticists in order to ascertain accuracy in identification of the Y chromosome by morphologic criteria. Results showed that this approach is subject to error, especially if the quality of the spreads is not very good.

Cytological Map of Human Y Chromosome
Human Heredity, 1986The 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.

Molecular dissection of the human Y-chromosome
Gene, 2002Human Y chromosome, earlier thought to be gene deficient, has attracted a great deal of attention owing to its supremacy in male sex determination and unique haplotype status in the genome. Studies on Y chromosome have shown the presence of different types of satellite DNA and several genes implicated with a variety of physical and physiological ...

Functional Coherence of the Human Y Chromosome
Obstetrical & Gynecological Survey, 1997A systematic search of the nonrecombining region of the human Y chromosome (NRY) identified 12 novel genes or families, 10 with full-length complementary DNA sequences. All 12 genes, and six of eight NRY genes or families previously isolated by less systematic means, fell into two classes.

The Length of the Human Y Chromosome
Cytogenetic and Genome Research, 1967The length of the human Y chromosome was measured and compared with the mean length of the group E (16–18) chromosomes in ten cells from each individual in the following groups of subjects: 30 control individuals; nine members of three randomly chosen families; ten members of four families with extremely long Y chromosomes; and ten members of three ...

Repeated DNA of the human Y chromosome
Development, 1987ABSTRACT A significant fraction of the human Y chromosome is composed of DNA sequences which have homologues on the X chromosome or autosomes in humans and non-human primates. However, most human Y-chromosome sequences so far examined do not have homologues on the Y chromosomes of other primates.

Autoradiographic studies of the human Y chromosome
Chromosoma, 1971An autoradiographic analysis (using continuous labeling with tritiated thymidine) was made on 317 cells from four normal males. The labeling pattern of the Y chromosome was compared to the first and the last chromosomes to complete replication as well as to G21–22.

Sequence variation of the human Y chromosome
Nature, 1995We have generated over 100 kilobases of sequence from the nonrecombining portion of the Y chromosomes from five humans and one common chimpanzee. The human subjects were chosen to match the earliest branches of the human mitochondrial tree. The survey of 18.3 kilobases from each human detected only three sites at which substitutions were present ...

A synopsis of the human Y chromosome
Human Genetics, 1980Phenotypic features and functions known to depend on the presence of the Y chromosome or the H-Y antigen are discussed in relation to structural anomalies of the Y chromosome and other abnormalities of sexual and somatic development. Recent knowledge about molecular organization of constitutive heterochromatin in relation to the human Y is presented ...

Human–mouse cell hybrid with human multiple Y chromosomes
Nature, 1976HUMAN–mouse cell hybrids usually exhibit preferential loss of human chromosomes1,2. After a time interval, which depends in part on the cell types used, most or sometimes all the human chromosomes segregate out from the hybrid cells3. In the course of investigation of the phenomenon of preferential loss of human chromosomes from hybrids between the ...
