Autosomal DNA statistics describe the connection between the genealogical relationship between two people and the amount of autosomal DNA which they share. Understanding this connection is critical to interpreting the results of an autosomal DNA test. Autosomal DNA is inherited equally from both parents. The amount of autosomal DNA inherited from more distant ancestors is randomly shuffled up in a process called recombination and the percentage of autosomal DNA coming from each ancestor is diluted with each new generation.
When interpreting autosomal DNA statistics, one must be careful to distinguish between the distribution of shared DNA for given relationships and the distribution of relationships for given amounts of shared DNA. For example, known second cousins on average share Conversely, the relationship between pairs of individuals sharing There are two simple mathematical methods of calculating the percentages of autosomal DNA shared by two individuals. The autosomal DNA of two related individuals will be half-identical in regions where each has inherited the same DNA from one parent, and ultimately from one common ancestor.
In the cases of siblings and double cousins, their autosomal DNA will be fully identical in regions where each has inherited the same DNA from both parents or from two more distant common ancestors respectively. Full siblings are half-identical on regions where each has inherited the same DNA from exactly one parent and fully identical on regions where each has inherited the same DNA from both parents. The first method of calculating percentages displayed by 23andMe expresses the aggregate length of the shared segments i.
The second method of calculating percentages to which those relying on FTDNA or GEDmatch must resort expresses the aggregate length of the half-identical or better regions as a percentage of the aggregate length of both sets of autosomes paternal and maternal. The maximum value that the numerator in this percentage can take is the length of one set of autosomes say the paternal ; the denominator if the length of two sets of autosomes maternal plus paternal.
