What Does DNA Testing Tell You?

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. Therefore, it helps you learn your ancestral origin and to where you actually came from.

First thing that genealogist needs to start with the DNA testing is the father to son linkage that tracks the Y-chromosome which only men have. In relation to this, they can start observing the Y-chromosome which shows in people and begin to compare them to be able to know where actually the paternal link is present. 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. This is an effective testing method that allows accurate tracking that could date back generations of your ancestors as a result of its mitochondria.

Not like the DNA found in nucleus, it changes as the environment is changing and therefore can be altered, mitochondrial DNA is more of a direct connection from the child to the mother that couldn’t be changed or modified. The genealogists are able to determine the maternal linkage by simply getting a sample of the maternal DNA. By acquiring such information, once again, it lets them find lost cousins or even celebrity ancestors.

Can this be very effective in terms of tracing family line and how they could tell who you are 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 key here, however, is for them to compare DNA profiles of other people consistently to what your profile is. To make things simple, this is creating a massive database that can help in determining piece of code that is comparable to yours. With this in mind, when the database keeps on growing, it becomes more useful in linking people to both their relatives and ancestors.

Aside from that, doing the DNA tests helps in showing where you originally came from. It is argued that 170000 years ago, humans have left Africa and has migrated somewhere else. Some of our ancestors have settled 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 the reason why carrying out DNA testing to find ancestors is now growing in popularity throughout people.
