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.
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. This makes it possible for the genealogist to learn about the paternal links among people. Linking the maternal DNA is also another procedure that can be performed. This is very powerful testing method which enables accurate tracking that can date back several generations due to 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. 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 getting such information, it allows them to find your lost cousins or even celebrity ancestors.
Could this be really effective when it comes to tracing family heritage and also, how they can tell who you’re related? Some websites focused on ancestry create DNA database against yours that can be a match. By taking mouth swab and running the DNA tests, they save the DNA profile that’s collected. 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.
What’s more, DNA tests can find out 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 the researched ethnic groups makes it possible to provide valuable details where people actually came from. This is the reason why carrying out DNA testing to find ancestors is now growing in popularity throughout people.
