Your Not The Father

Sibling DNA Test Same Father

Are you uncertain whether you and an alleged sibling share the same biological father? If you answered yes. Please continue reading this post.

Today, I will share with you the different types of siblingship scenarios I have experienced as well as the sibling DNA testing types that will be best suited for your specific situation.

Over the last 14 years, the most common scenario I have encountered is when two believe they may share the same biological father. Sometimes these people come together over an estate battle due to the biological father dying or, one of the siblings doing family research due to one sibling being adopted.

Regardless of your reasoning, the specific name for this type of DNA test is known as a half siblingship DNA test. This test determines whether two possible siblings share the same biological father . So if you are looking to perform this DNA test it is important that you inquire about this specific type of DNA test. Often times people who inquire about this test ask for a DNA test without describing their situation. Even if you do not remember the name of the test. Make sure you give a good description to the company you decide to use the type you need. You will be surprised how many people have complained about not getting the type of DNA test needed they wanted correct. Miscommunication is not too excessive in this industry to my knowledge but, It does exist often enough for me to want to make you aware of being clear and concise about what you are trying to accomplish.

Another common DNA test performed is known as a full sibling DNA test. This determines if two siblings share the same mother and father. Normally, people who request this type of DNA test need to provide proof to some sort of legal institution like a USCIS or the passport agency. Nonetheless, making sure you clear to the DNA testing company of your choice about what you are trying to accomplish is key to make sure you get exactly to you are looking for.

How accurate is a sibling DNA test?

The accuracy of a sibling DNA test will depend on how many people are available to partake in the DNA test and, How many markers the laboratory uses to perform a DNA test. For example, if you are trying to perform a half sibling DNA test to determine if two siblings share the same father. If available the mother of at least one sibling would help strengthen the half sibling DNA test.

Siblingship Testing Types

Full Siblings vs. Unrelated

This test determines whether siblings share the same mother and father. Also, this type of sibling test is most frequently requested in U.S. immigration cases, in which one individual is a U.S. citizen sponsoring an alleged sibling who is applying for an immigrant visa.

Full Siblings vs. Half Siblings. In these sibling tests, the DNA of two individuals with the same biological mother is compared to determine the likelihood that they have the same biological father. It is recommended that the mother partake in the DNA test. This test enables a lab to determine exactly which genes the two children inherited from their biological father and thereby greatly increases the conclusiveness of the test.

Half Siblings vs. Unrelated. In these sibling tests, the DNA of two individuals with different biological mothers is compared to determine the likelihood that they have the same biological father. For these tests, we recommend that samples from one—and preferably both—biological mothers be tested if possible. This enables a lab to determine exactly which genes the two children inherited from their biological father(s) and thereby greatly increases the conclusiveness of the test.
