This technique involves analyzing for markers on the autosomal chromosomes whereas Y-DNA analyses involve markers on only the Y-chromosome and mtDNA analyses only on mitochondrial DNA. Unlike Y-DNA, which is only derived from your father, and mtDNA, which is only derived from your mother, autosomal DNA is derived from both parents. Thus, by analyzing for markers on the autosomal DNA one obtains information about all your ancestors, male and female. Autosomal DNA is a complex amalgam of DNA from your ancestors, the contribution from each being diluted through each generation. However, it appears that one can identify relationships as distant as fifth cousins.
