Some Jewish groups like Jews for Judaism reject wholesale the claims of the LDS that the conversion to Mormonism reveals a familial connection between the convert and ethnic Jews. They base their position on Judaism's interpretation of Hebrew scriptures and advances in biological science, saying "No amount of genetic testing or DNA sampling will show the Jewish people and the Latter-day Saints to be of the same ancestry. The Latter-day Saints are simply not of Israelite origins... For all their assertions and genealogical research, the Latter-day Saints are not descendants of Joseph and can never join Judah in fulfillment of a nonexistent prophecy."
