Thanks for the responses. I have asked for clarification on the way 23andme is reporting the pair of chromosomes a few times and haven't gotten any answers. So, am I correct in my understanding that 23andme is not distinguishing between the pair of chromosomes in their reporting? Wouldn't it make more sense to report them in a way that differentiates between them - like Chr #1A and Chr #1B? It is going to make it very difficult to triangulate the results to determine from which ancestral line groups of matches descend. For example, I have a spreadsheet where I enter all of my matches. I have been assuming (apparently incorrectly) that if the match falls on the same chromosome in the same or overlapping spot, then we all share a common ancestor. If all the matches are at 23andme, I guess the answer is to determine if they all match each other, however, I was hoping to be able to enter RF and FF matches on this spreadsheet in the future and "see" matches between the two companies.
Am I understanding this correctly or am I missing something?
Thanks again for the help,
