Relationship DNA testing encapsulates a number of very specific tests which are designed to determine whether specific relationships exist between alleged relatives and can help you solve any doubts you may have. Any relative can take part in a relationship test including aunts, uncles, cousins, grandparents and siblings. This test can really help you clarify whether biological ties exist between alleged relatives.
The Following Are the 3 Main types of relationship tests if you wish to find answers to any doubts you may have
A sibling DNA Test: A sibling DNA test can clarify a number of issues such as whether you are full, half or no siblings at all. This test can thus tell you whether you share one parent or both parents or whether you have no parent in common. Often siblings seek such a test because they need to know whether or not they share the same father but their father is not available for the DNA test. Whenever the father is available for testing, your safest bet is a paternity DNA test as this is far more accurate and reliable than a sibling DNA test.
An X chromosome test is typically used between females. Two females may want to know whether they share the same biological father; in some cases they may have to include the sample of the mother just to ensure the result is clear-cut. A Y chromosome test can be done between males who wish to determine whether they share the same father.
Grandparents DNA Test: A grandparent DNA test can involve just one grandparent or both. It is often carried out in lieu of a paternity test and if both grandparents are available then it will also be possible to re-construct the missing father’s DNA profile. The foundations for the test rely on the fact that grandparents will pass on their genes to their son who in turn will pass those genes to his child. The test can accurately tell whether the grandparent/s tested is the biological grandparent/s of their grandchild.
Avuncular DNA testing: this DNA relationship test involves testing the father’s full siblings in cases where the father is unavailable for testing. An aunt or uncle will share common genes with their niece or nephew though not anywhere as close as the number of genes shared between parent and child.
The testing methodologies used depend on who is actually available or willing to be tested and importantly, the gender of those involved. Relationship DNA testing is, as mentioned, an umbrella term for a number of test.
