The human Y chromosome: a masculine chromosome

Current Opinion in Genetics & Development, 2006
Once considered to be a genetic wasteland of no scientific interest beyond sex determination, the human Y chromosome has made a significant comeback in the past few decades and is currently implicated in multiple diseases, including spermatogenic failure - absent or very low levels of sperm production.

HUMAN CHROMOSOME Y AND SRY

Cell Biology International, 1996
AbstractThe precise location of the SRY gene on the human Y chromosome has been revealed through studies of sex reversal cases involving deletion, cross‐linking and mutations of the SRY gene. Its DNA sequence and mechanism of action are being understood.

Evolution of human Y-chromosome DNA

Chromosoma, 1982
We have used human male-specific 3.4 kb Hae III restriction endonuclease fragments to explore the evolutionary history of man's Y-chromosome. We have identified four sets of reiterated sequences on the basis of their relative sequence homology with autosomal DNA.

The Y Chromosome in Human Spermatozoa

Nature, 1970
ATTEMPTS have been made to distinguish between spermatozoa of mammals containing either an X or a Y chromosome by looking for differences in size and surface properties of the two classes of cells (see refs. 1 and 2 for reviews), but the results of such approaches are equivocal.

Subdivision of the human Y chromosome

Human Genetics, 1974
The normal human Y chromosome was subdivided into 6 distinct bands by Q, C bandings and microdensitometric tracing. The best results were obtained from chromosomes not fully condensed. The results reveal that at late prophase the Y can be subdivided in 1 single unstained band in short arm 5 bands in the long arm.

Human Y-Chromosome-Specific Reiterated DNA

Science, 1976
Radiolabeled reiterated DNA specific for the human Y chromosome has been obtained by extensive reassociations between [ 3 H]DNA prepared from men and excess DNA from women. These highly purified labeled sequences reassociate only with DNA from individuals with a Y chromosome.

Human evolution and the Y chromosome

Current Opinion in Genetics & Development, 1996
The past two years have seen the increased study of Y-chromosome polymorphisms and their relationship to human evolution and variation. Low Y-chromosome sequence diversity indicates that the common ancestor of all extant Y chromosomes lived relatively recently and the consensus of estimates of time to the most recent common ancestor concur with ...

Mapping the human Y chromosome

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1988
This paper reviews past and present trends in mapping the human Y chromosome. So far, mapping has essentially used a combination of cytogenetic and molecular analyses of Y-chromosomal anomalies and sex reversal syndromes. This deletion mapping culminated recently in the isolation of the putative sex-determining locus TDF
