Several years ago I had my DNA tested for both my Y-chromosome (father to son) and mitochondrial (mother to child). It was an interesting exercise. My Y line is haplotype I2a. Someone just yesterday emailed me about it. It lead me to an unanswerable question. How many men living in the year 1000 A.D. (or CE for those of the PC persuasion), have an uninterrupted line of male descendants today with their Y chromosome? The email stated:
I myself am the volunteer administrator of the Polish Project. I happen to belong to I2a also. Your closest match at 37 markers in Ysearch is a Ukrainian who is a genetic distance of 10 away from you. In other words, your pattern of marker values is somewhat unusual.
Could it be that very few Slavic men have an uninterrupted male line done to 2008? Or am I "somewhat unusual?" Or perhaps not enough of the general population has had their DNA tested to give a decent statistical outcome? Who knows? [P.S. I'm Slovak through my male line, at least back to 1700.]
