what is autosomal dna testing
English. 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).utosomal DNA tests can be used to confirm relationships with a high level of accuracy for parent/child relationships and all relationships up to the second cousin level.
A recent breakthrough in DNA testing for genealogy is a new form of autosomal DNA testing. This type of test checks your autosomal chromosomes, the other 22 pairs beyond the sex-linked X and Y chromosomes.n autosomal DNA test can introduce you to those cousins who have taken the same test. Some of your newfound cousins will have genealogical information that you lack. By comparing notes and pooling your resources, you both win. Genealogists also use this test to confirm suspected connections between deceased ancestors.
