Ancestry DNA Test

Many families are now exploring their family trees in search of the origins of their ancestors. One incredible tool that is now available to those researching their roots is ancestry DNA testing. These tests have no medical value but compare a person’s DNA to that of those throughout history. Successful tests can tell a person their family’s county of origin, paternal migration routes and can even find relatives who share the same DNA code.

DNA testing ancestry begins with the scraping of the tissue on the inside of the mouth to collect a sample for testing purposes. This is then sent out to a laboratory where the genetic information contained in your tissue is translated into a series of encrypted numbers. Using this information, the technician can compare the results against data collected over the last twenty years to relay information about your ancestors.

DNA Testing for Ancestry

Male DNA ancestry testing has a lot more information available to them as the Y chromosome is passed directly from father to son. That means that the Y-chromosome in a male today is identical to his ancestors thousands of years ago. Using a Y-DNA test, the results can be matched against one of 18 paternal lineages, referred to as haplogroups, to determine which broad geographic area your family originated from. Using additional markers in your DNA, the analysis can further break down the location. For instance a haplogroup may identify Africa but additional analysis can find what region in Africa your ancestors are from.

Female or maternal DNA ancestry testing uses mitochondrial DNA, or mtDNA testing, to determine the maternal line. While a mother’s DNA is passed from mother to child, a male child does not pass it on to their children so the information collected is not as plentiful as the Y-DNA test. A DNA test can determine the broad geographic region based on one of 30 maternal lineages that have been discovered to date. You can also have the migration patterns of your family from as far back as 170,000 years ago.

Results from ancestry DNA testing generally takes 6 – 8 weeks but can deliver a wealth of knowledge concerning your genealogy.
