MITOCHONDRIAL TEST - US$ 295

BROTHERS Y TEST
  • Mitochondrial DNA is only herited from the Mother, so it is the ideal test to see if siblings have the same biological mother.
  • The accuracy of the test depends very much on the type of mitochondrial DNA you have. If two matching persons have a rare type of Mitochondrial DNA then they are more likely to be siblings, than two persons who match with a common type of
    mitochondrial DNA. The probabilty of you being related is calculated after we know
    what type of DNA you have.
