DNA ancestry test is needed when you want to know about your family history. In some cases, it is used for legal purposes also. We can determine our ethnicity group with the help of DNA testing and also can know about family relationships. Even, from where our ancestors came, it can be known from this testing. In paternity disputes, it is very helpful.
There are some criteria for doing this testing are described below
Y Chromosome Testing
This testing is done on males because Y chromosomes are only found in males. In knowing a father-son relationship, this testing plays an important role. In Y chromosome testing, we can know about that same surname people are related to each other or not.
Single Nucleotide Polymorphism Testing
This testing is done when we want to know the entire race or ethnicity of an individual. In this, the entire genome of a person is checked. We can know the all ethnicity history like European, Asian and African. By this testing, we can know the overall ethnic background.
Mitochondria also store some DNA and both males and females have mitochondrial DNA. So, the major benefit of this testing is that you can do this on females also.
All these DNA testing are done in the presence of experts. From taking samples to a laboratory test, all work is done carefully. In case of privacy, you can use the Faceit DNA kit at home. You can get services at any location where you want. For getting better DNA testing services in California and Texas, you can search Ancestry DNA test California and Ancestry DNA test TX. Faceit DNA testing in Los Angeles is also available.
There are also some limitations of DNA ancestry test. In some conditions, estimates don’t come accurate because of a complex history. As the ethnicity of a person revolves around many changes in a wide frame of time. So, it is tough to get accurate results in such scenarios. In the case of having many SNPs, it is really tough to distinguish people who have the same common ancestor.
