It confirms what was found by the study: <br />"Admixture occurred<br />with North African non-Jewish populations. However, as<br />demonstrated by the apparent unrelatedness of the Jewish and<br />non-Jewish North Africans, these events were not recent."raffi17https://www.blogger.com/profile/16292819479004954330noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-28606472338654170472012-08-09T01:03:24.880+03:002012-08-09T01:03:24.880+03:00Sephardic Jews are very diverse compared to Ashken...Sephardic Jews are very diverse compared to Ashkenazi Jews. A similar finding was reported in the recent Graham and Coop paper in which Germans shared more IBD with Poles on average than with each other.<br /><br />The best way to think about this is by drawing a trapezoid like this:<br /><br />http://en.wikipedia.org/wiki/File:Trapezoid.svg<br /><br />if AB is much longer than CD, and h is small, then random points in AB are usually further apart than they are to CD.<br /><br />So, populations with reduced genetic diversity (such as Balto-Slavs, a very recent population expansion, or AJ, a quite recent population isolate) tend to IBD share a lot.Dienekeshttps://www.blogger.com/profile/02082684850093948970noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-73381359208961638142012-08-09T00:34:16.399+03:002012-08-09T00:34:16.399+03:00How is that Sephardic Jews share a larger IBD with...How is that Sephardic Jews share a larger IBD with Ashkenazic Jews than with each other?Auditor George Danoshttps://www.blogger.com/profile/15451291978096556616noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-55531181601910747422012-08-08T22:44:16.430+03:002012-08-08T22:44:16.430+03:00Really interesting.
