DNA Testing For Authentic Search Of Ancestry


Something that can really penetrate into your origin and give your birth identity along with ethnic proof is DNA testing. There is often a confusion regarding the genealogical DNA test. It is thought to detect genetic defects and disorders. But in fact the DNA test has nothing to do with disorders but to state your ancestral identity and its authenticity.

Basic DNA testing procedures

The DNA testing process is conducted by taking a DNA sample and that is very simple. A cheek-scrap is taken with the help of chewing gum or the conventional cheek swab and this sample is mailed for the final testing in the lab. The DNA tests related to bring out the ancestral history has been categorized broadly into two types. You must have heard of the Y-DNA testing and the Mt-DNA testing. Y refers to the Y-chromosome that determines the sex and Mt stands for mitochondria.

The Y-DNA test is done to find out the ancestry of a man because the Y-chromosome is the determining chromosomal factor that the baby will be a male or a female. Therefore this particular chromosome is inherited by the son from the father. The paternal side identity is marked by the Y-chromosome.

When the era enchants on gender equity, what about the mother's identity and how can that be decided through DNA testing? Mitochondrial DNA testing is exactly done to bring out the mother's identity. Mitochondrial testing of the DNA is conducted by taking the reference from the coding region present in the mitochondria and Hyper Variable Regions which are double in number. And it is considered that when the mitochondria in the DNA pass from the mother to the child, no change takes place.

Popularity of DNA testing

In recent times the genealogical DNA testing is in vogue. It has become the simplest tool to find out your origin and a trail of your ancestors. The genealogy is decided right sitting at your home because the DNA sample can be taken so easily in both the tests. Further you can cent percent rely on the authenticity of the test.

If the determination of the relationship of an individual with another is a little doubtful or cannot be tracked, you need not lose hope because the genealogical DNA testing is full-proved to bring about whether the relationship is true and genuine. So associating your existence with your ancestors has become so readily available with the mere examination of the nucleotides stored in the human DNA. Was it possible even a century ago? Hats off to Genetics and Microbiology to bring about this revolution!
