Y-STR haplotype tools (modals, genetic distance, TMRCA)
The following is a selection of tools that can be used for a set of Y-STR values (DYS etc.) including calculating the time to the most recent common ancestor.
- Dean McGee's Y-DNA Utility Ysearch/FTNDA Mode, also for up to Y-DNA111 markers for Genetic Distance and TMRCA tables. It can output to PHYLIP and Fluxus for building phylogenetic trees, etc.
- The Ethio Helix Y TMRCA Calculator - two different calculators with one for STRs and one for SNPs
- TiP - the Family Tree DNA Time Predictor tool (only for FTDNA Y-DNA12+ customers)
- The Clan McDonald TMRCA Probability Calculator Graph or List
- Moses Walker's Most Recent Common Ancestor Probability Calculator Probability of Relationship %, Generations to MRCA
- Phylofriend Open source program that calculates genetic distances from Family Tree DNA projects to create phylogenetic trees with PHYLIP.
- Y-DNA Family Grouping App A free app created by Chase Ashley that allows people to quickly and easily (1) analyze surname project STR results to determine appropriate family groupings and (2) compare a particular project kit against all other kits in the project
- SAPP (Still Another Phylogeny Program). Web based interface. Takes a plain text data file (*.txt) as input. which contains the STR results, SNPs, and Genealogies for SAPP to use in building the phylogenetic tree. See the blog post from Maurice Gleeson L2 MHT - "difficult to place" people for a description of its use.
- Tim Janzen in 2008 has developed a program in Excel that does intraclade TMRCA estimates for large numbers of Y STR haplotypes. It may be downloaded from http://www.timjanzen.com/dna.html.
- Ken Nordtvedt has a program in Excel that does intraclade and interclade TMRCA estimates for Y STR haplotypes (Generations111T.xlsx only available from web.archive)
Y-STR haplogroup prediction tools
The accuracy of haplogroup prediction based on Y-STR haplotypes depends mainly on the number of STR-values. Without SNP confirmation prediction for low-resolution haplotpyes (Y-STR12 to Y-STR24) has a low value of confidence and convergence can be a problem. For many haplogroups Y-STR25 to Y-STR37 has an acceptable confidence level while for some young haplogroups with rapid diversification and expansion like in R1b even Y-STR67 is not enough to discriminate the correct sublineage with confidence. A few scientific studies are available. [1] [2] [3]
