DNA Relationship Testing

Relationship DNA testing can assist to determine whether there really are biological links between relatives. This type of test can be performed between various degrees of relationships including siblings, grandparents, aunts and uncles.

Why do a DNA Relationship test?

Generally, people might opt to do such a test as a means of establishing paternity in cases where the father is not available and therefore, a straightforward paternity test is not an option. In such cases a grandparentage test or an avuncular DNA test can substitute a paternity DNA test. Siblings may also do a sibling DNA tests, which will establish what type of siblings they are, half siblings, full etc.

Here is a list of the DNA tests available:

• Siblings DNA test: determine whether you are half or full siblings or not related at all. We can establish these relationships by doing different type of tests – read more to find out your options.
   
• DNA Avuncular Testing:  can act as a substitute test for a DNA paternity test. With this test is carried out on the alleged father’s relatives together with the alleged father’s child.
   
• DNA Grandparentage Test: testing the grandparents and their grandchild will tell us if the grandchild’s father is the biological father or not. Genetic material present in both grandparents will be present in the grandchild if the grandparent’s son is genetically related to his son.

• Y chromosome Test: The test is done only between males as the Y chromosome is only. possessed by males. It is commonly done to see if the males share the same paternal line.
   
• X chromosome Test: This test informs you if alleged sisters share the same father.
