Before everything else,brand new part of DNA mutual between personal family relations wasn’t what you to anticipates observe
Once i fell the standard values on Gedmatch so you can a hundred snps/step one cm I started initially to get a notion as to the reasons they’d for example uncommon mutual rates. Around the all their chromosomes, the results have been just as the numbers below:
