Family DNA Results

I posted my genetic ancestry results. Now, we’ve got my parents, my sister and my wife tested with 23andme. So I thought a comparison would be interesting. Here’s the ancestry painting from 23andme which uses three reference populations: Yoruba from Nigeria, Chinese and Japanese, and Utahns of Northwestern European descent.

My Biogeographical Ancestry

There are several different ways to figure out your genetic ancestry. One way that 23andme shows your ancestry is by comparison with reference populations of the HGDP (Human Genome Diversity Project) dataset. I have listed how similar I am to various groups in the table below: Reference Population Similarity Groups Included Central & South Asians… Continue reading My Biogeographical Ancestry

Ancestry Painting

23andme has a feature called ancestry painting which gives you the percentages of different populations you are admixed from. In my case, I got the following: European 91.22% Asian 8.69% African 0.09% Ignore the precision (to 2 decimal places). I showed that because I wanted to highlight the nonzero African ancestry percentage which I will… Continue reading Ancestry Painting

Paternal and Maternal Lines

We men inherit the Y chromosome from our fathers who got it from their fathers. So the Y chromosome can be used to trace your paternal lineage. Different sequences of alleles and mutations can be assigned to haplogroups where a haplogroup signifies common descent on the uniparental line. According to my 23andme results, I belong… Continue reading Paternal and Maternal Lines

Harappa Ancestry Project

I have become interested (some would say obsessed) with genetics recently. I wrote about getting my DNA test done and there’s a lot more about my own results that I plan to bore you with. One fun application of genetic testing is inferring ancestry: Which ancestral group are you descended from? Can we estimate the… Continue reading Harappa Ancestry Project

Personal Genomics: DNA Test

Last year in April, 23andme were having a sale for DNA Day, selling their 550,000 SNP test with ancestry and health information for $99 instead of its regular price of $499 at that time. So I decided to take the plunge and sent my spit from the East coast to the West to be analyzed.… Continue reading Personal Genomics: DNA Test
