One of my cousins (half Norwegian) on Dad’s side (all Norwegian) just got his results. So I made this chart comparing myself to my 1st, 2nd, and 3rd cousins on Dad’s side. Mind you, the 2nd cousin is on Dad’s paternal side while the third cousin is on his mom’s side.
My brother’s chart looks very similar except no X match of course. Notice the very large X match I have with my first cousin which would come from his mother and my Dad’s mother, 57.3 cM. Interesting to see this as compared to my Dad ….
These are the same three people as compared to my Dad. Notice the randomness of what I got, one would expect about half of the DNA he shares with them to be passed to me but I got more than half of what he shares with my first cousin and less than half with the other two
Dad shares 24.1% with his nephew while I share 12.7%. With my 2nd cousin he shares 5.23%, while I share 2.34% according to 23andme. ISOGG has some statistics about family relationships listed at this url: http://www.isogg.org/wiki/Autosomal_DNA_statistics
Having all this data makes it easier to attempt to track down more distantly related “DNA cousins.” Now I can go back and compare my 1st cousin to all of them and see what I can learn. I have heard that http://www.dnagedcom.com/ will be adding this feature … (comparing someone you share with versus everyone else you share with). Hope that comes soon!
