As I have mentioned before, cousin marriages were fairly common among my family. My parents are first cousins. So are my father’s parents. My mother’s parents are second cousins once removed. So instead of 32 great-great-great grandparents, I have only about 18. Since my wife and I are not related, I wondered how my inbred… Continue reading Outbreeding Works in a Single Generation

Zack Ajmal Phased Genome
A few months ago, I made my DNA genotyping results from 23andme public. Since I got results for both my parents as well, I have now used BEAGLE to phase my genetic data. In simple words, I have been able to separate the contribution of my Dad and my Mom on my DNA. I am… Continue reading Zack Ajmal Phased Genome
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. Dad Mom Sister Me Wife… Continue reading Family DNA Results
Genome in the Wild
I tested with 23andme in April 2010 and then upgraded to their version 3 chip with almost a million SNPs last Christmas. Now I am releasing my personal genome in the public domain. To the extent possible under law, Zack Ajmal has waived all copyright and related or neighboring rights to Zack Ajmal 23andme v3… Continue reading Genome in the Wild
Genome Similarity
23andme has a feature where you can find out how similar your genes are to your friends and family (who you are sharing with at the site). The result is a bar list with percentages showing similarity. The number next to each person in the bar list is a measure of similarity. Specifically, it is… Continue reading Genome Similarity
Inbreeding
I have found out I am actually from West Virginia. Ok, I am just joking. I knew that my family had a history of marriages among relatives. After all I have only 10 great-great-grandparents instead of the usual 16. With my genome in hand, I set about to quantify the inbreeding. First, I used David… Continue reading Inbreeding
Harappa Project New Site
As several people had asked, I have set up a separate website for the Harappa Ancestry Project at http://www.harappadna.org/. I am keeping a link to the new site on the top menu bar here titled Harappa DNA. I might also crosspost some items from the project here. I have also set up a Facebook page… Continue reading Harappa Project New Site
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
