Recent genetic research, however, has shown that many Latinos of the American Southwest may be descended from
Anusim (Sephardic Jews who converted to Roman Catholicism). Michael Hammer, a research professor at the University of Arizona and an expert on Jewish genetics, said that fewer than 1% of non-Semites, but more than four times the entire Jewish population of the world, possessed the male-specific "
Cohanim marker" (which in itself is not necessarily endemic to all Jews, but is prevalent among Jews claiming descent from hereditary priests), and 30 of 78 Latinos tested in
New Mexico (38.5%) were found to be carriers. DNA testing of Hispanic populations also revealed between 10% and 15% of men living in New Mexico, south
Texas and northern
Mexico have a
Y chromosome that traces back to the Middle East.
