Wondering if you’re related? You can confirm your biological relationship with a sibling DNA test. This test will verify if you are half siblings, full sibling or not related at all.
Avoid questioning others and use an authentic DNA testing method to resolve all your doubts.
What is Sibling DNA Testing?
DNA test compares your genetic code with another DNA to determine the similarities and differences between DNAs. This test is generally used to determine if two people have the same (biological) father. Sibling DNA testing is performed in cases where the father is dead or unwilling to take the test.
This test aids many legal cases. For instance, if a mother wants to obtain social security survivor benefits for all her kids, she can conduct a sibling DNA test to prove that the children are from the same father. Moreover, immigration test and application process sometimes require sibling testing to prove family ties.
Types of Sibling DNA Testing
l Full Sibling vs. Half Siblings
This test is conducted between individuals who have the same biological mother. The DNA samples are compared to determine if the siblings have the same biological father. The conclusiveness of the test can be improved by testing the mother’s DNA as well. This will allow the tester to identify genes inherited from the mother specifically.
- Full siblings vs. Unrelated
This DNA test is conducted to determine if two individuals have the same biological father and mother or whether they are completely unrelated.
- Half siblings vs. Unrelated
DNA of two individuals, who have completely different biological mothers are tested to determine if they share the same biological father.
A DNA sample is collected from both mothers to identify the genetic inheritance in children’s DNA. Accurate test results can be achieved if the tester clearly knows which gene was inherited from the mother’s side.
The accuracy of sibling DNA testing can vary, as DNA sample of one or both biological parents are missing from the equation. Children share similar genetic code as their parents, which can easily be identified in a paternity test.
However, the same level of accuracy cannot be achieved by comparing two sibling’s DNA. The accuracy of the test hugely depends on the availability of genetic information of the parents and the nature of relationship being tested.
Generally, full siblings share 50 percent of the same genes (due to a common biological parents), whereas, half siblings share only 25 percent of the same genetic code.
