I'm entering my uncle's mtDNA results from FamilyTreeDNA into mitosearch. But I ran into two problems that their help doesn't seem to answer.
Problem 1: FamilyTreeDNA provides differences from two different reference sequences: RSRS (the Reconstructed Sapiens Reference System) and rCRS (the revised Cambridge Reference System). Which one do I enter into Mitosearch?
Problem 2: See the dropdown in the above image. It allows entry of the four nucleotides A, C, G and T. My uncle's mutations include some heteroplasmy, which is the presence of more than one mtDNA sequence in a cell. They are represented by different letters. In my uncle's case, one of his mutations has a Y, which I understand to represent C or T. How do I enter this into Mitosearch?
