The Big Tree: R-A9063
A242A red SNP name with a '?' indicates that the SNP's status for the block is uncertain, but assumed to be negative. The same SNP probably occurs in a parallel block. It will be necessary to check BAM files or perhaps Sanger sequence some men to prove the result.
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.
