It is now becoming more common to use DNA testing to identify a person’s lineage. By linking maternal DNA and paternal DNA, the ancestry databases can be linked to other people whom you might be related to effectively. This helps in figuring out more about your ancestral origin and at the same time, to know where you came from.
First thing that a genealogist require for DNA testing is father to son linkage which tracks the Y-chromosome that only men have. With this in mind, they will be able to observe the Y-chromosome appearing in people and begin to compare them in order to know where the paternal link could be in. In essence, doing such comparison allows the genealogist to know more about the paternal links among people. Another thing that could be done is by linking maternal DNA. Its mitochondria lets it track several generations of your ancestry, making it as the most powerful and effective method.
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 maternal DNA, which is different compared to DNA in nucleus, genealogists are now capable of determining maternal linkage. This information they have on hand is so valuable in finding out about your 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. Simply speaking, this creates massive database that helps in instantly determining if a piece of code is direct comparison to you. For this reason, the database starts to grow more and more and it helps to link people to their relatives as well as ancestors.
Aside from that, doing the DNA tests helps in showing where you originally came from. It has been said that 170000 years ago, humans migrated their home from Africa. With some went to Southern Africa, Europe and others went to Asia. Comparing DNA profile of a person to that researched ethnic groups, it’s feasible to provide valuable info where people came from. This is why performing DNA testing to find ancestors is starting to amass popularity amongst people.
