“You may cite biased experts but anyone of sound mind knows a religion can never create a genetic marker.”
>>>It is not the religion which creates the genetic marker. It is the People who have the genetic markers, no matter what religion they practice. The Biblical Jews were a people who practiced Judaism and lived together in communities where they married other Jews.. Their descendants who moved away still retained the same genetic markers. Over hundreds and thousands of years, many of these Jews mnarried non Jews who converted to Judaism. Thei children of such marriages had a mixture of Jewish and non Jewish DNA. Any converts who converted to Judaism eventually had their DNA added to the mixture. The main thing about Jews is that they ARE a people, they act as a people, they live as a people and they share religious and cultural practices and beliefs.Secular and athiest Jews easily fit into this peoplehood, unless they actively abandon it. The reason that different populaltions of Jews have differen percentages of the Jewish DNA and of European or Middle Eastern DNA is simply that as the Jews scattered, most still clung to their culture and at least part of their religious parctice.Certainly over the centuries, many Jews abandonned Judaism and became Christian, Muslim or another religion
