Uses of an X chromosome test?
- This test can be used if two females with different mothers want to determine whether they have the same biological father.
- In cases where two females share the same mother, it is still possible to do an X chromosome test; however, we will need the mother’s sample. Having the mother’s sample will enable scientists to know which X chromosome was inherited from the mother and which from the father.
- The X chromosome test can be used between paternal grandmother and granddaughter as they must share one X chromosome. This shared X chromosome is the one that the grandmother passed to her son and he, in turn, passed to his daughter. We only need DNA samples of the paternal grandmother and granddaughter for this test. We require no other samples in this particular case.

More about the test
Our X chromosome test is done by extracting a 10 marker profile from the females tested.Women have 1 X chromosome pair in every cell – they inherit one X chromosome from their father and one from their mother. While men have only one X chromosome inherited from their mother. Female offspring will always have one of their X chromosome which is inherited from their biological father. DNA testing will confirm a match for the paternally inherited X chromosome.
