It is now becoming more common to use DNA testing to identify a person’s lineage. By simply linking the maternal and the paternal DNA, the ancestry databases could find a match to other people whom you might just be related. Therefore, it helps you learn your ancestral origin and to where you actually came from.
To get started with the DNA testing, the genealogist will first require the father to son linkage, which is basically the Y-chromosome. For this reason, they can observe the Y-chromosome that appears in people and start comparing them to know where the paternal link might be present. In essence, this comparison lets genealogist to find the paternal links among people. Another thing that could be done is by linking maternal DNA. This is an effective testing method that allows accurate tracking that could date back generations of your ancestors as a result of its mitochondria.
The DNA found in nucleus is changing as the environment changes and for that, it is altered; when compared to mitochondrial DNA, it stays as is because it’s a direct connection from mother to child. By getting a sample of the maternal DNA which is different than the DNA in the nucleus, it helps the genealogist to determine the maternal linkage. By acquiring such information, once again, it lets them find lost cousins or even celebrity ancestors.
But can this be effective in regards to tracing family line and how is it possible for them to know who you’re related to? There are websites that are about ancestry that have created DNA database and match it against yours. They save the DNA profile collected by simply getting a mouth swab and run DNA tests. The secret here is comparing the DNA profile of other people consistently to know your profile. To make things simple, this is creating a massive database that can help in determining piece of code that is comparable to yours. Therefore, as the database begins to grow more and more, it helps in linking people to their ancestors and relatives.
What’s more, DNA tests can find out where you originally came from. It’s argued that around 170000 years ago, humans left Africa and migrated somewhere else. Some of them have gone to Southern Africa, Europe and others went to Asia. Comparing DNA profile of a person to the researched ethnic groups makes it possible to provide valuable details where people actually came from. This is why performing DNA testing to find ancestors is starting to amass popularity amongst people.
