This is summary of one of two current articles about using a 600,000
markers.

My summary

Landmark study proves 90% of Jews are genetically linked to the Levant
Jews in communities around the globe show more genetic similarities with
each other than they do with their non-Jewish neighbors, except in India
and Ethiopia. The only three exceptions were the Jews of India,
Ethiopia, and Georgia, who had more similarity to their host nations
than to other Jewish communities. The international study, led by
researchers >from Rambam Medical Center in Haifa and the Technion -
Israel Institute of Technology, mapped the Jewish genome for the first
time. The research encompassed communities representing most of the
world's Jewish population.
The study also showed the genetic ties between the Jewish people and
other peoples of the Levant: In communities representing 90 percent of
the Jewish people worldwide, Jews were more genetically similar to
non-Jewish Levantines than their non-Jewish hosts were.

Researchers >from eight countries - Israel, Britain, the United States,
Russia, Spain, Estonia, Portugal and Italy - compared 600,000 genetic
markers in 114 people >from 14 Diaspora Jewish communities and 1,161
people >from 69 non-Jewish populations.

I hope you find this interesting.
