Y-Chromosome-Test

J. is 45. His father died one year ago. J. did not want to cause his elderly father undue stress and never asked him if he would be prepared to have a paternity test. J. has become more and more troubled by the thought that his deceased father was not his biological father. There were rumours for as long as he can remember. He wants confirmation. J. has a half brother from his father’s second marriage. Together with his half brother, J. decides to have a Y-Chromosome-test carried out to confirm that they both have the same biological father.
