HarappaWorld at Gedmatch.com
Gedmatch.com
Are you part pygmy?
The admixture utilities seem to be, at least to me, one of the best features of Gedmatch.com. The results are beautiful, instantaneous. and you can go from one admixture program to another in minutes.
There is now yet another admixture program to plug your data into, and it is just as much fun as the others. This one is called HarappaWorld, and has some intriguing ethnic groups as reference points for the admixture. I had never heard of some of them.
Anyone who has raw data from autosomal testing will enjoy this new utility. You can compare the results of two kits (say you and your uncle) to each other and see the painted colors representing ethnic groups on each chromosome. It is amazing and wonderful that genetic scientists are willing to put up these utilities on Gedmatch.com for anyone to use. It enriches everyone's understanding and curiosity.
Yes, I'm intrigued. The results bring us as many questions as answers, and that is half the fun.

New Admixture models (PLURAL!) will take your data at Gedmatch
I can hardly keep up with the new features that keep appearing at gedmatch.com.
There are new, well-designed models for admixture of your genetic heritage available at Gedmatch. Just put in your kit number (assuming you have had your DNA tested), if you have already put your data in the system--and if you haven't, be sure to upload it according to the instructions--it is simple. Then click and wait.
You can choose to have results analyzed by Magnus Ducatus Lituaniae Project feature.. The blog which explains it is available here: http://magnusducatus.blogspot.com/e.Magnus Ducatus project.
Or you can enter your data into the Davidski Eurogenes K12 feature for admixture analysis.
Or you can use the Dienekes Dodecad admixture feature.
Or, of course, try using all three and compare the results. All three provide chromosome painting.
They are all amazing and your results appear immediately.
The results show up in a color pie graph broken down into heritage areas: Paleo Mediterranean, East Eurasian, West Eurasian, Caucasian, South Asian, etc.
See how your heritage looks according to this model.See Gedmatch.com.
And...there is a new feature at gedmatch.com for comparing segments from two people on one chromosome. It is so much easier than piling everything into a chromosome browser and scanning for results in common with someone else.

Gedmatch is now doing admixture...and chromosome "painting!"!
There is a new and wonderful addition to the gedmatch.com website. It is an admixture feature, now in beta version. For example, it will show your percentages, as measured in your DNA, of what compares to populations such as West European, South Asian, etc. For Americans with varied ancestry, it provides a very interesting glimpse into family history.
Just very recently, a feature called "Genetic Admixture Painting" was added. It is amazing. It gives you a lot of bang for your buck when you test your DNA because it expands your options for using the raw data.
If you have loaded up your autosomal test results onto Gedmatch.com, you can just put your kit number into the admixture feature, and there it is. Very interesting, and convenient. Whether it is accurate or not, and bear in mind that it is in its beta version, it certainly gives more of a breakdown into different reference populations than the Population Finder at FTDNA.
Click on the image to see the breakdown.
I look at these admixture breakdown results, wherever I can find them, as informative and fun. As admixture testing improves, results will improve. For now, at least in my opinion, it is to be seen as helpful, but not definitive, in identifying the backgrounds of ancestors.
Comments on the FTDNA forum indicated that the results are comparable to results done on the same samples with other analysts--geneticists, testing companies, scientists. It is important to take the time to look at the reference populations to get an idea of what the percentages mean. The reference population for West Asian might not be what you think of as West Asian, for example.
It is very useful to sign up for the blogs of Dienekes Pontikos, and to look at what he has done with his data. For those of us for whom analyzing numbers is not a natch, it is also useful to check out what professionals and amateurs have to say about all that at some of the forums such as DNA-forums.org. Another useful forum is at FTDNA.
Even more fun is the chromosome breakdown, showing the percentage of admixture on each chromosome! Take chromosome 22, for example. It will show say 22 % East European, 40% West European, 10 % East Asian, and so on. Again, not taking it as perfect science, I do plan to use it with the chromosome browser AND match results to see if I can get a better idea of my ancestry, especially as it compares with that of my matches.

The Genetic Admixture Painting shows your chromosomes, one by one, brought to life with vibrant colors indicating where on each the segments best match the reference populations. It is gorgeous and fun to look at while pondering one's possible ancestry. The picture below is of admixture.

The gedmatch.com utilities are free, and well worth looking into for anyone who is looking for more ways to analyze autosomal DNA test results.
Update April 7 2012: DNA forums is now gone.
