Since it is impossible for a religion to create a genetic marker my statement is both scientific and logical. There can be genetic markers with intermarriage but that applies to all religions until the group dies out because of genetic malfunction.
There is no genetic marker or DNA for any religion on the planet. It is simply impossible.
What is called Jewish/Ashkenazi DNA is also found in Christians, Muslims and probably Hindus, therefore categorically demonstrating THERE IS NO JEWISH DNA.
