Note: R-L21 and R-U106 are inconsistent and may indicate that this is NOT one genetic family but more than one.

Genetic Network

With grateful thanks to McGee Utilities and Fluxus Engineering, we calculated the genetic network diagrams below.

Fluxus Network, 37 markers

Reading the Fluxus Network Diagram

The network diagram gives a pictorial representation of how members of this genetic family may be related. It depicts inferred genetic branches of the paternal lineage and may be helpful in documentary research.

  1. The inference criterion used to build the diagram is maximum parsimony or "Occam's Razor". This criteria (fewest possible assumptions) may not be the most appropriate in all instances.
  2. The diagram is not proof; it is one interpretation of available geneitc data. Alternative interpretations may be possible.
  3. ySTR data is "noisy"; it contains some unexplained variability. .
Notes on the diagram:


The STR matches between conflicting haplogroups (R-L21 & R-U106) indicates that some of these matches may be coincidental, rather than indicating shared paternity. (R-M269 is upstream of both.) It is suggested that conflicts could be better delinatated, and perhaps resovled, with more STR and SNP testing.

TiP Scores

TiP Scores Explained

TiP (for "Time Predictor") is a utility provided by Family Tree DNA. It is accessible to all FTDNA customers with Y-DNA results who have matches listed within the FTDNA reporting windows. It is also available to project administrators for calculating the probabilities that any two project members share a direct paternal ancestor within up to 24 generations.

TiP is superior to most TMRCA calculators. Rather than assume an average mutation rate for all markers compared, TiP uses individual marker mutation frequencies. Because marker mutation rates vary significantly between markers, the TiP scores 

As we use it here, TiP is a truer and simpler measure of genetic distances between individuals than other metrics such as the number of markers in disagreement or a sum of the differences (sometimes called "genetic distance"). TiP boils the complexities down to one number.

The composite TiP score is an index of how closely a member matches the entire group. Generally, the member with the highest score is the central member.


Unless stated otherwise, TiP probabilities are from TiP version 1 (v1) in effect from August 1, 2012 to December 11, 2012. Another version was in effect from December 12, 2012 to January 17, 2013 and was replaced with version 3 (v3) on January 18, 2013. We are in the process of updating to v3. In the meantime, we've made some observations about how v1 and v3 compare:

Genetic distance from other groups

Groups R1b-64 and R1b-66 are closely related, with about a 51% overall chance of sharing a common paternal ancestor within 24 generations. The most closely-related other groups in Taylor Family Genes are

R1b-66 is the 16th most closely related to R1b-04 with a 17% chance of sharing a common paternal ancestor within 24 generations and R1b-64 is the 22nd with a 10% chance. .
