It's possible that a North African Berber might have some Sub-Saharan ancestry, although this will depend on the individual case; Berbers are by no means homogeneous.Dienekeshttps://www.blogger.com/profile/02082684850093948970noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-85784216228015920452008-09-24T22:28:00.000+03:002008-09-24T22:28:00.000+03:00I tested with both 23andme and Decodeme.

Indeed I am half Berber, half French (E3b1b-M81, MtDna =I) but my 23andme results showed 100% European (African and Asian =0% ) whereas my DecodeMe results showed 81% European, 13% African ancestry and 6% Asian. So both results are very different. And I think it is not possible when somoeone has half berber ancestry to not show at least > 1 or 2 % of African/Asian ancestry. (Also I am sure they did not mix my sample with someone else as my Y-dna and mtDNA haplogroups are the same for both companies)<BR/> <BR/>Do you know if these very different results can be because of different method used between 23andme and Decodeme ?Antoine1706https://www.blogger.com/profile/03897615920319105519noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-78478782554905435212008-09-17T18:17:00.000+03:002008-09-17T18:17:00.000+03:00Excellent insights into 23andMe in this post.

One implication is that the company might be interested in building the value of its own database by getting phenotypic and geneological information from its customers. To my knowledge, this is not the case.<BR/><BR/>It seems likely that the problems of matching genotype and phenotype are seen as currently insurmountable. If potential-customer skittishness about privacy already loom large, a series of probing questions could drive many away. Further, unvetted information could make such a database unreliable.AMachttps://www.blogger.com/profile/08872008617279528583noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-91556355370815229352008-09-16T13:41:00.000+03:002008-09-16T13:41:00.000+03:00Who do you think will be the first one to provide ...<I>Who do you think will be the first one to provide a "kit" where people can do these kinds of genetics tests in their own homes (without having to go to any 3rd party)... with the ease one has for home pregnancy tests.
