This is my latest assignment from Family Tree DNA:
BY-1551. This was an assignment from the National Geographic Geno 2.0+ data set. If you look at Big Tree ( go to link. Search for BY1551. click on it) and also the BY-1551 test at YSeq, they both say the normal base at this location is Cytosine. But the raw data for my DNA says this base is Cytosine and yet also a mutation. This is an error in the assignment of the data.
