Scientists know that the Y chromosome has been shrinking in size over millions of years, but recent studies suggest that it has more important genes, besides the ones that cause biological maleness.

David Page describes the odd history of the Y chromosome, its apparent loss of genes and its presumed fragility. He explains the great difficulty of decoding the Y chromosome, and what scientists have discovered about its complex role in evolution. He also discusses an emerging interest in this field regarding the relationship between the sex chromosomes and conditions that affect males or females disproportionately: for example why autism affects males much more than females.

Y chromosome
The Y chromosome is one of two sex chromosomes (allosomes) in mammals, including humans, and many other animals. The other is the X chromosome. Y is the sex-determining chromosome in many species, since it is the presence or absence of Y that determines the male or female sex of offspring produced in sexual reproduction. In mammals, the Y chromosome contains the gene SRY, which triggers testis development. The DNA in the human Y chromosome is composed of about 59 million base pairs. The Y chromosome is passed only from father to son. With a 30% difference between humans and chimpanzees, the Y chromosome is one of the fastest evolving parts of the human genome. To date, over 200 Y-linked genes have been identified. All Y-linked genes are expressed and (apart from duplicated genes) hemizygous (present on only one chromosome) except in the cases of aneuploidy such as XYY syndrome or XXYY syndrome. (See Y linkage.)
Overview
Discovery
The Y chromosome was identified as a sex-determining chromosome by Nettie Stevens at Bryn Mawr College in 1905 during a study of the mealworm Tenebrio molitor. Edmund Beecher Wilson independently discovered the same mechanisms the same year. Stevens proposed that chromosomes always existed in pairs and that the Y chromosome was the pair of the X chromosome discovered in 1890 by Hermann Henking. She realized that the previous idea of Clarence Erwin McClung, that the X chromosome determines sex, was wrong and that sex determination is, in fact, due to the presence or absence of the Y chromosome. Stevens named the chromosome "Y" simply to follow on from Henking's "X" alphabetically.

Evolution of the Y Chromosome
David Page describes the odd history of the Y chromosome, its apparent loss of genes and its presumed fragility. He explains the great difficulty of decoding the Y chromosome, and what scientists have discovered about its complex role in evolution. He also discusses an emerging interest in this field regarding the relationship between the sex chromosomes and conditions that affect males or females disproportionately: for example why autism affects males much more than females.

Male Producing Y Chromosome Likely to Disappear, Says Geneticist Jenny Graves at ANU
http://www.globalpost.com/dispatches/globalpost-blogs/weird-wide-web/testicles-penis-male-y-chromosome-genetics-sex
"The Y chromosome that makes men is poorly designed and degrading rapidly, meaning it's likely to disappear even while humans remain on the planet, an evolutionary geneticist and "thinker in residence" at a leading Australian college says."
Men on Road to Extinction
http://www.telegraph.co.uk/science/science-news/5360172/Men-on-road-to-extinction.html
