X Chromosome Testing

Females have 23 XX chromosome pairs. One of the chromosomes in each pair is inherited from the mother and the other inherited from the father. The X Chromosome Test is used to establish if sisters with different mothers share the same father. The cost of the test with easyDNA UK is £329.

• In cases where two females with different mothers want to establish if they have the same biological father. Scientists will determine whether their X chromosome patterns match; if they do, it means they share the same father and are therefore, half siblings.
• In cases where two females share the same mother and want to establish if they share a biological father, an X-Chromosome test can be carried out but only if the mothers sample is available for testing. This will help determine which X chromosome was inherited from which parent. The test cannot be done in this case without the mother's sample.
