Y Chromosome Consortium
The Y Chromosome Consortium (YCC) was a collection of scientists who worked toward the understanding of human Y chromosomal phylogenetics and evolution. The consortium had the following objectives: web resources that communicate information relating to the non-recombinant region of the Y-chromosome including new variants and changes in the nomenclature. The consortium sponsored literature regarding updates in the phylogenetics and nomenclature.

Y Chromosome
The Y chromosome is one of two sex chromosomes (allosomes) in therian mammals, including humans, and many other animals. The other is the X chromosome. Y is normally 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 male development. The DNA in the human Y chromosome is composed of about 59 million base pairs, making it similar in size to chromosome 19. 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. The human Y chromosome carries an estimated 100–200 genes, with between 45 and 73 of these being protein-coding. All single-copy Y-linked genes are hemizygous (present on only one chromosome) except in cases of aneuploidy such as XYY syndrome or XXYY syndrome. ...
