How Autosomal DNA Testing Works

Natural selection is not a random process - or if your personal choice of autosomal DNA testing (for genealogical purposes) is random. Leave a genetic genealogist will guide you through the various tests available, so you know what they offer and provides the most cost effective for the average genealogist genetic approach.

Autosomal dna testing is useful for genealogical purposes. The autosomal DNA more you share with another person, which are more closely related to that person. In fact, the autosomal DNA comprises a majority of it is found in DNA and 44 of the 46 chromosomes. This type of test used to identify closely related, and cousins now about what you may have not known it relates.

There are three main companies that offer genetic DNA testing for genealogy purposes autosomal family: 23andMe, Family Tree DNA (FTDNA) and Ancestry.com. The evidence provided by these companies are similar in that they all use "SNP chips" test between 700,000 and 967,000 point mutations called SNPs (single nucleotide polymorphisms). The 23andMe test includes most SNPs in his essay.

All three companies offer a list of the closest matches in their database. The number of games you have depends on the amount of people in the database of the company, the number of people with their ancestral history that have been tested, and the criteria that the company assigns to what constitutes a match. AncestryDNA was the lowest for a match criterion, resulting in the most remote people appear in your list to match.

23andMe and FTDNA product ("Family Finder") both to provide information about specific segments of DNA that are shared with their games, including segments of chromosomes are matched on the number of SNPs in the corresponding segment and the start and stop positions on the chromosomes of each corresponding segment. This information is crucial for genetic genealogists trying to trace their family trees, from information by segments allows you to assign your chromosomes, which is to determine which ancestor or ancestral segments corresponding pair is inherited. AncestryDNA currently does not provide this information, which is a major drawback to this test; But the benefits of the test is that the phases of data before the match list is generated, which reduces the number of false positives that appear on the party list.

Each of the companies dealing with databases of different sizes. 23andMe currently has about 160,000 people in its database, FTDNA has about 40,000 people in their family ancestry search database and approximately 65,000 data AncestryDNA database. The 23andMe test provides information on health in the context of the trial, which is something AncestryDNA FTDNA Family Finder, or do not understand. A much higher proportion of people who took the 23andMe test was relatively limited genealogical research, which makes it difficult when trying to match your 23andMe contact. The tests are also available at varying prices - in the range of $ 200 to $ 300.

I think the most cost effective for the average genetic genealogist approach is to get a DNA test first, then import the raw data file in the database data FTDNA Family Finder, which currently costs less than $ 100 . This saves about $ 200 compared to the two control tests separately. You must be a member of the descent to try AncestryDNA, and you should receive a personal email from the company that invites you to take the test before you can ask for. I think it's reasonable for Ancestry.com subscribers to test AncestryDNA, but the people doing the test should be aware that there are significant drawbacks to this test compared to other tests, provides the first descent no data files to clients and provides no information on the corresponding segment.
