Family DNA testing is quite common, especially as it’s the perfect answer to all your family-related questions. Some people get this DNA test to kill their curiosity, and some have to do it for their documentation. The court might be demanding it, or your immigration and visa officer might request it. DNA testing helps confirm biological maternity, paternity, and your other family relationships. Families that consist of mixed races or those that don’t have proper documents usually get this. There are different types of relationship DNA testing. To learn more about family DNA testing, read further below.

Maternity Test

The purpose of a maternity test is to determine your biological mother. Every human being inherits half of their DNA from their biological mother and the other half from their biological father. A maternity DNA test proves if the mother has the same genes as the child. If she doesn’t, then it is a clear answer that she isn’t the biological mother. You may not need this test if you’re already getting a paternal test.

Sibship Test

You can easily determine the relationship between your siblings through a family DNA test. People carry out Sibship tests when they want to find out their relationship with another person. This DNA test works regardless of sex. You can also find out whether they’re your full or half-sibling.  If two siblings share the same DNA, then the genetic marker should be at least 50%. For half-siblings, the marker is at 25%.

According to these markers, lab technicians can then determine the chances if the siblings share the same DNA. A sibling DNA test isn’t 100% accurate as it’s hard to determine with certainty. However, the results are always on a likelihood scale.

Y Chromosome Testing

When it comes to paternity testing, it has a lot to do with the Y chromosome. Y chromosome passes on to males from a father to a son. With the help of these tests, you can determine if two men are from one paternal line. This line consists of siblings, cousins, uncle/nephews, and others. Even though this test links to a specific family line, it is still not very accurate. For example, it doesn’t have the ability to distinguish between brothers, paternal sons, cousins, and grandsons.

The samples from males go through polymorphic sites and then are compared. If the males share a common Y chromosome and are from the same paternal line, the test will come out positive. DNA paternity testing is around 100% accurate if conducted under the right procedure. The male handling has to be very effective when proving paternity test results.

Other Relationship Testing

You can also determine the biological relationship with your cousins, uncles, aunts, and grandparents through family DNA testing. These tests use DNA identification technology. Most of the results for this type of test occurs on the basis of likelihood. Therefore, there is a slight chance of an inconclusive result.

Reasons Why You Would Need To Get a Family DNA Test

Family DNA testing also helps with many official requirements and documents. These tests can also be for health purposes, knowing if you’re prone to a life-threatening disease. Mentioned below is the reason why you would need to get a family DNA test:

1.     Surrogacy Purposes

Surrogacy pregnancy may require testing, especially if the biological mother wants to confirm if the child is still hers. This is very common in gestational surrogacy cases. The DNA testing for this case will usually take place after the delivery of the baby. On the other hand, you can also carry out a prenatal test.

2.     Immigration Purposes

The USCIS has not made DNA testing mandatory. However, if there is no proof of the biological relationship between the people sponsoring you, there are further steps. The Visa counsel will advise you to get a family DNA test to gather more accurate proof. These tests have nothing to do with making the immigration process faster. All it does is remove any breaks and unanswered questions to get the process going.

3.     Adoption Purposes

If a mother wants to put her child up for adoption, then there will be a maternity test. Orphanages usually conduct these tests to prove that the mother is the biological mother of the child.

4.     Personal Purposes

You can also achieve a family DNA test for your own curiosity, especially when you haven’t got the right answers or documented proof. DNA tests bring you one step closer to finding out your roots if you’re not sure of them.

Family DNA Testing: The Bottom-Line

DNA testing surely does helps prove family relationships to a certain extent. That is especially the case if they are your immediate families like your mother, father, and siblings.
