Introduction to Y-chromosome DNA
The human Y chromosome is a male-specific sex chromosome. Nearly all humans who possess a Y chromosome will be morphologically male. Although the Y chromosome is situated in the cell nucleus, it only recombines with the X-chromosome at the ends of the Y chromosome; the vast majority of the Y chromosome (95%) does not recombine. When mutations (errors in the copying process) arise in the Y chromosome in the form of single-nucleotide polymorphisms) or short tandem repeats, they are passed down directly from father to son in a direct male line of descent. This line is known as the patriline.
The Genome Reference Consortium maintains the reference assembly of the human genome. The GRC tracks issues relating to the Y chromosome such as gaps and errors in the sequence. Details can be found here. The GRCh37 build of the Y chromosome has a length of 59,373,566 base-pairs, but only 25,653,566 base-pairs are actually positioned. Build 38 (GRCh38) was released on 24 December 2013.[1]

How To Search
The easiest way to find pages is to type the subject of interest into the Search Box on the top left of your screen. As you type, a drop-down list of pages will appear. Click on a suggested page to view it or click the very bottom of the list where it says "containing" to view every mention of the search term in the ISOGG Wiki. Many pages have shortcuts so that, for example, if you type in SNP you will automatically be taken to the page for single-nucleotide polymorphism and NPE will take you to the page for non-paternity event.
