Introduction to Autosomal DNA

Autosomal DNA is a term used in genetic genealogy to describe DNA which is inherited from the autosomal chromosomes. An autosome is any of the numbered chromosomes, as opposed to the sex chromosomes. Humans have 22 pairs of autosomes and one pair of sex chromosomes (the X chromosome and the Y chromosome). Autosomes are numbered roughly in relation to their sizes. That is, Chromosome 1 has approximately 2,800 genes, while chromosome 22 has approximately 750 genes. There is no established abbreviation for autosomal DNA: atDNA (more common) and auDNA are used.

Tips for Searching the Wiki

The easiest way to find pages is to type the subject of interest into the Search Box on the top-right 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 atDNA will take you to the page for autosomal DNA.

The Contents Page provides a thematic list of all the pages in the ISOGG Wiki. Additionally the Wiki can be searched from the Index, an auto-generated alphabetical list of all the articles in the ISOGG Wiki. Alternatively you can browse the pages by searching the Category Tree.
