DNA testing might sound overwhelming since it consists of terms that we aren’t well-acquainted with. If you are pondering on the question that whether you should opt for a DNA testing or not, here are some things you need to know about DNA testing.
Types of DNA testing
There are three types of DNA testing that an individual can choose to undergo. They are:

- Mitochondrial DNA Test (mtDNA) Test– This form of DNA testing makes use of the cellular powerhouses called mitochondria to trace the individual matrilineal heritage. Since the mother gives the mitochondrial DNA to the baby irrespective of whether it’s a boy or a girl, men and women can take this test.
- Autosomal DNA Test: Autosomal DNA tests can be taken by men and women alike. Also, autosomal DNA tests are quite functional since it can trace all of your family lines, unlike the previous forms of DNA testing that can trace either of your family lines, patrilineal or matrilineal.
It is common knowledge that DNA testing is highly personal, and you wouldn’t obviously like this information to become public. Authentic DNA testing sites ensure their users maximum security regarding their results. Majority of DNA testing sites do not claim ownership rights to the DNA you submitted for testing.
If you opt for an ancestry DNA test, it would measure your DNA at about approximately 700, 000 locations across your genome. Then, it takes the data acquired in the search and compares it to the genetic data assimilated from over 150 globally distributed regions.
