I am a genetics graduate student, and thus am really interested in my own genetic history. Here is the thing, this Ancestry composition application said I was 0.4% Sub-Saharan African. I got quite excited about this as it runs contrary to all the family history I have been given. The split view showed that all of this would have come from my mother. This was when I only had my father's genotype (0.0% African). <br /><br />Well today I got my mothers information and it says she is 0.3% sub-Saharan African. Obviously both of these results can't be true (I can't be 0.4% African if my mother is 0.3% and my father is 0.0%). At first I was pretty dubious about the African heritage at all. Do you know how likely it is that all of my African heritage is an error or how likely it is that it is real?Anonymoushttps://www.blogger.com/profile/11951776526780825120noreply@blogger.comtag:blogger.com,1999:blog-4773058005679938889.post-25842121481348087502013-01-01T22:53:15.308-08:002013-01-01T22:53:15.308-08:00spidermum said...

I seem to be the point person in my husband's family for capturing his family tree, and also his DNA information, and I have a question relating to male-cousin testing. Previously, my husband had gotten his predicted Y-DNA and mt-DNA haplogroup results including 37 Y-markers, which I shared with his family. Now hubby wants to have his male cousins tested, too. The question I have is whether the 23andMe autosomal test would also provide equivalent haplogroup assignments and Y_DNA STR marker data that we could then compare to my husband's data. I looked up the Illumina OmniExpress Plus Genotyping BeadChip, and it did not appear to provide any mt-DNA results. For the cousins, their autosomal test results would be of some mild interest, however, their family trees are not well populated for comparison purposes. I love the new test pricing at 23&Me, but I am beginning to think the FamilyTreeDNA tests for haplogroups plus STR markers would give the boys the best overview of their DNA heritage. Please give me a little insight into this choice.

I'm a little more than half as Scandinavian as my mom. So guess that's how those things shake out. <br /><br />I've tried to get my siblings to test and one is less enthused because of the spitting and one because of the cost. Hopefully highlighting the recent coolness and the price drop will get them invested.

Someone who hid their identity or converted so young they don't know. Perhaps even a child who escaped the Holocaust by living with a non-Jewish family.

Does your brother have a matches on his Y-DNA test with Ashkenazi heritage? If so, then it is your father's father that gave you your Jewish ancestry, which fits very well with your findings on Family Finder. It sounds like the majority of your matches are from that unknown grandfather, so there is good reason that you don't recognize the surnames. Do you have the surname Benjamin in your known family tree? If so, that certainly would suggest that there is Jewish ancestry from another line as well. I would also test your brother on Family Finder to make sure that you are full siblings and don't have different fathers. <br />Thanks for your comment. You can write to me privately if you wish.<br />CeCeYour Genetic Genealogisthttps://www.blogger.com/profile/14696248341534125135noreply@blogger.comtag:blogger.com,1999:blog-4773058005679938889.post-56922977558830070392012-12-20T03:41:41.159-08:002012-12-20T03:41:41.159-08:00Everyone receives 50% of their autosomal DNA from ...Everyone receives 50% of their autosomal DNA from each parent, so half of your ancestry is from your dad regardless of the fact that you don't have a Y-Chromosome. (23andMe tests autosomal DNA.) Your son will not inherit any DNA from your father that you don't pass to him, therefore testing him is less beneficial than testing his father unless you just want to see the 50% that your son inherited from you. If your husband doesn't want to test, then testing your son will show you the half of your husband's DNA that your son inherited.<br />I hope this makes sens too.

I have been researhing my family for 15 years now so I am not new to genealogy but am so confused with the DNA component and hope that you can provide some answers - please forgive my ignorance! Since I am female so I have no y chromosome so do I miss out on my father's whole family history? I was originally going to order a kit for myself and my huusband (although he doesn't really want to :) ) but now that I read your "split screen" talk above would I be better off ordering one for me and my 7 year old son? This way I would get my information on my report and connect it to my son and then I could see what information he received from me and what he received from his father's line and any new information on my line would then be obviously from my father? I hope that made some sense - it is still early in the morning.JM @ Gertz and Mayshttps://www.blogger.com/profile/03744409338802716450noreply@blogger.comtag:blogger.com,1999:blog-4773058005679938889.post-59524640830559444722012-12-11T11:03:36.587-08:002012-12-11T11:03:36.587-08:00My autosomal DNA results are very confusing.

I have no Jewish ancestry that I know of and have a family tree that goes back to the 1500 and 1600s. According to people I have spoken to, I should have 1 grandparent who is Jewish but I don't know who that would be. None of the names that others are researching are familiar at all except for 1 person with whom I match with the surname Benjamin. What do I do with this information? I was adopted but found my birth family. My brother has tested his DNA but only the Y-DNA. We don't know who our father's father was as his mother was not married when he was born. What would you suggest I do to try to unravel this mystery?Natalie14612https://www.blogger.com/profile/11133262748979550774noreply@blogger.comtag:blogger.com,1999:blog-4773058005679938889.post-24202903740189446932012-12-10T11:50:04.392-08:002012-12-10T11:50:04.392-08:00It's there, but not obvious.

I HOPE 23andMe DOESN'T MAKE THIS MISTAKE IN THEIR UDPATED ANCESTRY ANALYSIS. <br /><br />In other words, just because someone has genetic markers that occur in, say, 10% of Africans, and also occurs in 90% of Europeans, doesn't mean that they should be classified as 10% African and 90% European. If you are European in origin, then in all likelihood, that marker came from Europe, not Africa or Asia. To assign a percentage to African or Asian is simply a jump I wouldn't be willing to make as it incorrectly assigns a racial component that is false (and potentially false by a large amount).Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4773058005679938889.post-16743730161187654182012-12-08T10:24:53.084-08:002012-12-08T10:24:53.084-08:00Any word on whether or not they (or anyone) plan t...Any word on whether or not they (or anyone) plan to sub-divide the Ashkenazi category?

Why do these results make Europeans appear to be a less homogeneous group than other ethnic groups, when studies have shown that the opposite is in fact true? Why are sub-Saharan Africans and Asians lumped together in very broad categories, when in those areas, especially Africa, there is the greatest genetic diversity?<br /><br />I understand that they are a company and their customers are mostly European descendants, but it would be a very easy thing to infer misleading conclusions about one's ancestry due to the way this information is presented.<br /><br />Furthermore, we ALL have African ancestors. There is not one human alive who is not related to another human being. I understand you mean RECENT ancestry, but again we must be careful how this sensitive information is presented.<br /><br />Thank you.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4773058005679938889.post-11239204250689626132012-12-07T01:02:47.491-08:002012-12-07T01:02:47.491-08:00GEDmatch also provides a very nice tool for ethnic...GEDmatch also provides a very nice tool for ethnical composition made by Vadim VerenichAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-4773058005679938889.post-78913069048002392782012-12-06T23:49:16.204-08:002012-12-06T23:49:16.204-08:00Actually Mike Macpherson is the one who pointed it...Actually Mike Macpherson is the one who pointed it out in his post introducing Ancestry Composition today.<br />Thanks for your comment,<br />CeCeYour Genetic Genealogisthttps://www.blogger.com/profile/14696248341534125135noreply@blogger.comtag:blogger.com,1999:blog-4773058005679938889.post-12563967807771837252012-12-06T23:17:23.554-08:002012-12-06T23:17:23.554-08:00The Ancestry Composition tool is great.
