From the 15th century on, Spain's Jews were mostly expelled or forced to convert, but today some 20 percent of Spaniards have genes similar to Sephardic Jews, a study has found.
A report in the American Journal of Human Genetics says almost a fifth of Spaniards have genes similar to Sephardic Jews. With a population of more than 40 million, Spain may thus have 8 million citizens with "Jewish" genes.

"The genetic composition of the current population is the legacy of our diverse cultural and religious past," study author Francesco Calafell, on the evolutionary biology faculty at Barcelona's Pompeu Fabra University, said Friday. Along with researchers from Leicester University in England and the Wellcome Trust, the study compared DNA samples from 1,140 men in Spain, Portugal and the Balearic Islands with established data on Moroccans, Algerians, and Sephardic Jews in Istanbul and Israel.
"The work shows that religious conversions and subsequent marriages between people of different lines had a significant impact on modern populations both in the Balearic Islands and in Portugal," another author Elena Bosch said in a statement.
Jews lived in Spain before the Moors arrived and although small in number played a significant cultural and economic role. It has been argued that Christopher Columbus, who set sail for the new world the day before Jews were to be expelled in the Inquisition of 1492, was himself. The childhood ditty may have to be revised:
"Columbus sailed the ocean blue
Who'd have guessed Chris was a Jew?"
Hundreds of thousands of Jews were expelled from Spain in various repressive moves, started by the Catholic Monarchs. The study suggests many Jews converted rather than face repression. Some Sephardic communities to this day speak Ladino, which is similar to medieval Spanish and can be understood by present-day Spaniards. "Marranos" or "Conversos" secretly carried on Jewish traditions.
