What To Expect From A Genealogy DNA Test

Using a genealogy DNA test is a great way to help broaden the range and scope of the family tree. However, it must be understood that the genealogy DNA test can only establish so much information. Here is what you can expect to learn from this type of test.

Identify Ethnic Backgrounds

Essentially, the genealogy DNA test is a good way to identify ethnic backgrounds that are part of the biological history of any given individual. Certain information, referred to as DNA markets, will help to indicate the presence of different attributes that are known to be indicative of particular ethnic groups. This makes it possible for persons who usually identify as part of one ethnic group to find out if there are ancestors of a different ethnic origin somewhere in the family line. This added information can often help amateur genealogists to research avenues of information that may have been overlooked or not considered otherwise.

Identify a Connection

A genealogy DNA test can also help to establish a biological connection between two persons of a current generation, by identifying a common link with an individual of a previous generation. For example, two persons may suspect that they share a common great grandparent, but lack any written documentation to prove the fact. Securing samples from both the two parties, as well as a sample from the ancestor, such as a hair sample or some other cellular material, can be used to identify common links between all three samples and confirm or deny the existence of a familial connection. While the genealogy DNA test will not define the exact nature of the connection, it will prove a connection exists, which can help the genealogist to find ways to research the family line and find the points of connection between the two parties.

One common use of the genealogy DNA test is to establish a connection between persons who share a surname, but who may come from branches of the same family that have resided in different parts of the country or the world for generations. For example, a person who lives in the United States, and comes from a family that is known to have emigrated from Great Britain at some point in the past, is able to confirm or deny a biological connection to a British subject who carries the same surname. The establishment of this connection can often allow the genealogy enthusiast to greatly expand the scope of the family genealogical detail, and provide access to a great deal of additional information about the history of the family line.
