And I am really convinced that we will never know the the whole facts. But it is clear when one reads most of the respected DNA-studies. That the Asheknazi have and admixture of European and Middle Eastern DNA. But the question remains witch one is the most?

They write "European" when they mean mostly Eastern and part of Central Europe-pretty arrogant considering that Greek and Roman Jewry predated there being any such thing as an Ashkenazim by 12-15 hundred years, and Rome has the longest continuous community in all of Europe! Wake the f#@% up Jew=Ashkenazi is as racist as the pre-Civil Rights white gentile attitude toward blacks. What year are these people living in?! <br /><br />In any event, the last study I saw showed only 50% Jewish ancestry in most edoth* studied-except the ones that were lower, so 100% is a hubristic and ludicrous number We know little if anything solid about the 9 1/2 tribes of the Northern Kingdom, and if you want to go by the Rabbinic decision to switch to matrilineal descent**, Dinah's descendants. <br />*Socio-geographic communities Yemenite, Iberian, Roman, Ethiopian, Eastern European, etc.<br />**I believe that decision was dubious-possibly overstepping the mandate for the "chachamim" to change what was indicated by the written Torah. Considering that Genghis Khan has at least 17 million patrilineal descendants, the implications I find staggering. Maybe a billion Jews by real p'shat Torah reckoning? At least a half-billion. I think one has only to look at those they know (and even more so Ashkenazim)to see that the fathers genes tend to be dominant more often than not-in either sex of offspring.

One would be Middle Eastern population movement into Europe during neolithic times . The theory was proposed by Prof. Luigi Luca Cavalli-Sforza at Stanford. Although he overestimated the neolithic genetic component in Europe overall, there is a clear clinal signature of neolithic expansion into Europe that is highest in the southeast (Greece, Balkans) and declines towards the northwest. The second would be intermarriage between Jews and local populations during the period of the Roman Empire. There were sizable Jewish communities in Roman Alexandria, western Anatolia, Greece, and Italy.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-32414509.post-10753403212108831932009-01-28T00:41:00.000-07:002009-01-28T00:41:00.000-07:00I am not a geneticist nor a statistician, but it s...I am not a geneticist nor a statistician, but it seems strange for a group of scientists to claim 100% sensitivity and 100% specificity. Other writers and readers have also addressed this point.

As one with a statistical background (but not in genetics), I have never seen a screening test or diagnostic test with 100% sensitivity and specificity (or, as the correct terms here would be, predictive value positive and predictive value negative).anonymoushttps://www.blogger.com/profile/07132472965888548368noreply@blogger.com
