The Big Tree: R-Y125244
CTS4296Mutations written with a red background fall within a region of the Y chromosome, such as the palindromic region, which has left the position of the mutation ambiguous. The true mutation may be at the indicated position, or at any one of a number of alternate positions.
Z18068SNP names which are bold grey indicates that their exact position on the tree is uncertain. This SNP may belong further upstream or all downstream branches may not be positive for it. This is often the case for SNPs found in FGC kits or 1kG kits in regions not covered by BigY tests.
