Hi
I am doing some research into my roots and was wondering if anyone else has done their DNA and found that they have mtDNA Haplogroup C.
This is is the DNA which is inherited solely from your mother, and can be passed by her to either sons or daughters. However it can only be passed to the next generation in turn, by the female line inthe family.
mtDNA is rare in the world population and I would like to contact anyone else on the forum who has got this genetic marker.
thanks

No takers? OK. Can I ask if any of you have family stories of transmigration from "the north". If so, have you been able to establish just how far north your family originated? The reason I ask is that I am an equatorial born daughter of a Southern GuangDong father and a mother from Fujian stock. However my mitochondrial DNA says that I am descended from the Evenki who live in the far north of Siberia. But although we have stories of northern origin, they don't include rheindeer!

Yin, A belated welcome to the forum. During the holiday season I missed your posts. Very few people have had their nuclear DNA checked. My naive perception is that even fewer have had their mitochondrial DNA evaluated. You might ask companies which have a larger database, such as 23&me ( www.23andme.com/) (given all the controversies? www.genetic-future.com/2008/01/uk-controversy-over-23andme.html). I hear that to submit your nuclear DNA it is around U$D400-U$D500. Chinese genealogy had always been about the paternal lineage (the Y chromosome). It is only recently has there been interest in the maternal lineage. As you note, this is how one can trace via biological markers the maternal line. It sounds like you had your mitochondrial DNA evaluated. Let us know the where's, why's, how's, costs, and your experiences. Tell us more about the your experience with haplogroup C ( encyclopedia.tfd.com/Haplogroup+C+%28mtDNA%29) Doug

My mother gave me a gift of a kit from National Geographic's The Genographic Project. genographic.nationalgeographic.com/genographic/index.htmlMy mtDNA resulted in Haplogroup F. My uncles says that MANY generations back, we came from the north, but settled in south, Toisan. Haplogroup F routes are found both in northern and southern China. It was interesting to note that I'm Haplogroup F, and confirmed that I'm Chinese, but didn't do much else for me in terms of revealing information. --Tamiza

Tamiza, What else did you learn from the kit? The service from National Geographics allows tracing either the maternal and paternal groups (with the Y chromosome) Chinese genealogy lineages have always been paternal, until recently. ¿I wonder how detailed is the mapping of the mitochondrial DNA (mtDNA)? ¿Will it allow tracing closer relatives rather than just populations?

Yes, for men, you can do either, but for women, they are only tracing through the maternal line, or mtDNA, so that's all I have.
I also learned the path of Haplogroups that I come from, from Mitochondrial Eve (L1/L0 to L2 to L3 to N to R to F)
I also learned how my mtDNA sequence differs from the Cambridge Reference Sequence. This information can be used to trace more details on origin, but I don't think they're quite there yet with the science (need more data collection) for everyone.

According to Wikipedia, genetic testing of Han Chinese show that men from the North mated with local woman to the South. The article on Han Chinese goes into much detail about genetic variations.

I had my DNA tested by 23andme. I am female (Chinese on my mom's side) and my haplogroup is D4a. I got my racial breakdown as follows: 47% European, 53% Asian (same as my research indicates). What is slightly interesting or news to me is the specific difference between D4 and D5 haplogroups. From the 23andme explanation: "Haplogroup D in Asia There are two major branches of the D haplogroup in Asia. D5, which is comparable in age to D itself, is common in southern China but rare farther north. D4, a younger haplogroup that arose about 35,000 years ago, is more common in northern Asia, reaching 18% in southern Siberia. Haplogroup D4 is particularly common among Koreans, where it reaches nearly 22%, and is present at about 20% in Manchuria, which is just north of the Korean Peninsula. Recent archaeological discoveries suggest that the earliest inhabitants of Korea probably came from the Alta-Sayan and Baikal regions of Southeast Siberia. They likely began to move into the region by about 30,000 years ago, when they followed mammoths and other large animals into the Peninsula." So my haplogroup is a newer one than many Cantonese it seems, more recently migrated from the north (only 35,000 years ago, how recently ). Of course I know many Cantonese anciently came from the north, but I didn't think I would be lumped with DNA of people more indigenous to Korea and such. The other thing about D4a is that it's been linked to populations with extreme longevity, and also esophageal and thyroid cancer, great. The test results give you tons and tons of scientific predispositions for your health based on your dna. Stuff like, I have high than baseline risks for celiac disease, type 2 diabetes, high blood pressure, etc. But lower than average risk for bipolar disorder, uterine fibroids, and other things I'm happy to know are less common for my genetic makeup. Everyone probably has some high and some lower risks for just about everything on their list. They also have less serious characteristic predictions based on dna: flushing of skin when consuming alcohol (negative for me, yay!), what sort of earwax I have, whether I can taste bitterness, muscle performance type (sprinter vs marathoner), etc. They have predictions for drug response as well - I am highly sensitive to coumadin apparently, not surprising, I already know my blood has a hard time clotting. The best and most interesting part of this whole spitting in a tube thing though, is the ability to connect with other test-takers who you actually share common dna with. Apparently I have a whole bunch of 4th cousins or so who have taken the test and whose dna matches partially to mine, enough to predict this distance for our genetic relationship. This works on both the maternal and paternal sides, even though I can get haplogroup results for mt dna only. The relative finder tool is based on chromosomal matches. So, recently I've come in contact with a 4th cousin (probable level of relationship) who is actually descended from folks who settled in Trinidad, and he believes we are related via the Chinese side as his grandmother was half Chinese. This is interesting to me in the way that I can hopefully learn and help my new cousin learn more about our common history and who exactly we are both descended from 5 generations back. Most of the other relative matches I've received are from Caucasian people, which is fine but just not what I am focusing on now. The relative finder tells you exactly where and what your chromosomal match is, and a percentage of shared blood. There is a cute mapping thing that shows how similar you are to populations throughout the world but it's hard to say how accurate or even useful that is given that all kinds of people live everywhere nowadays. It shows me as most similar to East Asians, and then a smattering of similarities to everywhere else in the world except sub-saharan Africa. Yeah I even got similarity hit to northern Africa. In this way, I sort of take it to mean that people in general are pretty similar genetically. -christine

I know this is an old thread, but I had to chime in. I had Y-dna (strictly paternal line) done on my father, who is largely Irish. It came back as being mostly middle Eastern in origin. It is rare for Irish people in this day and age to get the Haplogroup he did (G2). And these were fair people carrying blonde hair and blue eye traits. So, while unique, it's not unheard of. That said, perspective is everything. Going back tens of thousands of years, ANYTHING is possible. I mean that. While it's likely you'll find something predictable, it's also very likely you'll find something slightly surprising. Siberian direct maternal lineage going back tens of thousands of years doesn't even sound surprising at all to me. I mean, think of just how far back that is, and just how much moving around of all people, slowly, over time, has taken place since! By the time you get back to that era, your ancestors by count number in the billions I believe (even though billions of people did not exist at that time). For one out of billions to be Siberian... yeah, could be! To me, Siberian seems pretty normal to get if you have Chinese ancestry and are tracing strictly one maternal (or even paternal) line way back into pre-history. I mean, I have a Chinese friend who has a Russian great grandmother, and that threw me for a loop to hear about. I would never have guessed, and it fascinated me. Imagine how much change we can be exposed to over thousands of generations? Mostly, these mitochondrial and Y-dna tests are just curiosities, just for fun. It's amazing to dream and think of our most ancient of origins, before we were even recording anything in our histories. Without these tests, we wouldn't have had any idea of such things, but they do nothing to tell us of our cultural or ethnic identifications in the present day.

Christine, I was thinking of doing 23 and me, too! It seems really interesting.
My only thing is, I'd really like an autosomal percentage test done for me and my husband. They are considered much less accurate, but I'm so curious to see a rounded out view of what we genetically consist of, since I know so many genealogical questions will probably go unanswered in our lifetimes.
It looks like I have multiple tests to take. They are so expensive!

My brother did the Y-Chromosome test with Ancestry.com and the results said his Paternal Haplogroup was '03', "The Inventors". "Haplogroup 03 can be found at very high rates among the Han Chinese and originated about 30,000 years ago in south-eastern Asia and quickly migrated to central China. It is still associated with central China, but many present-day embers of Manchurian, Korean and Vietnamese populations are part of the "Inventors". Some Filipinos and Japanese are also in this group." Our father, Kai Yip Seto is from the village of Yen Ping, but I don't know where it is to see if it concurs with this test result.
I did my Autosomal DNA with 'DNA Tribes laboratory' and had to add the 'East Asian Panel'. My MLI scores were 66.24 Filipinos (Taiwan), 11.65 Milao (Guangxi, China), 7.72 Mulao (Guangxi, China), 6.74 Philippines, 4.63 Hui Chinese Muslim (China), and a whole list of smaller scores in other asian countries. This told me nothing concrete and I feel it was a waste of money.

lmurak With DNA testing, there are these 3 factors: 1. population sets are huge. 2. mingling of chromosomes are complete and random with each generation (2 23rd power) 3. number of people who can afford testing is small. Hence, the off chance of finding relatives or a close match is miniscule. Also, the population migration trends, like all nascent science, changes with every discovery. In the current status of genealogy, your most efficient method of finding a match is your family interview . You are probably correct and should save your money. IMHO Doug

Hi Doug, Thank you for your comments. I have been reading alot of posts on this website and have also posted at different forums. My problem is that I forget where I posted and do not make it back to read the responses or find them a week or so later. Is there a method that I am missing to find my way back? Thanks, Linda

Linda, The latitude-longitude coordinates of Enping urban area are "22.19, 112.33". By entering the coordinates into Google Maps search, you'll be able to locate the city.
Looking at the map, you'll see that Enping is in Guangdong province but close to the border with Guangxi. Guangdong and Guangxi are the 2 southern most provinces on the Chinese mainland. The words "dong" and "xi" mean east and west, respectively, which makes sense because of their relative location. Collectively, they are also known as the 2 Guang provinces, East Guang and West Guang.
The 2 provinces are geographically isolated from the rest of China by mountain ridges to the north. So up until roads were built a little over a thousand years ago, the provinces were sparsely populated by Yue tribes, which is the same people as the Vietnamese. The Chinese word for Viet is Yue, Nam means south and Vietnam is Southern Yue.
The early migration of people from central China to Guangdong came by way of waterways to Guangxi and then to Guangdong. Therefore, I think you and your brother's DNA showing shared heritage with Vietnamese and Guangxi people is consistent with this history and migration pattern.
