The MILLETT Surname DNA Project - Y-DNA Colorized Chart

For genealogy within the most recent fifteen generations, STR markers help define paternal lineages. Y-DNA STR markers change (mutate) often enough that most men who share the same STR results also share a recent paternal lineage. This page displays Y-Chromosome DNA (Y-DNA) STR results for the project. It uses the colorized format. The columns display each project member's kit number, paternal ancestry information according to project settings, the paternal tree branch (haplogroup), and actual STR marker results. The color coding of STR names is explained here. In the haplogroups column, haplogroups in green are confirmed by SNP testing. Haplogroups in red are predicted. Above each subgroup, we display the minimum, maximum and mode values for each STR marker in the subgroup. STR marker values that differ from the mode values are color-coded. You can read about the coding system here. You may learn more about Y-DNA STRs on the Understanding Y-DNA STRs learning page.
