A red background is used for men whose data has not yet been fully analyzed. His position on the tree is not yet final, and will in general be downstream of the current position. He may not be positive for all the SNPs/INDELs in the block he descends from.
Men whose NGS data have been fully analyzed are indicated with a grey background color.
SNP 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.
