About this Group
Haplogroup G exists at low levels in many places from Wales to Sri Lanka,
but in some places reaches frequencies as high as 40%. The National Geographic
Society pegs its origin in the Middle East about 10,000-20,000 years ago. A
unique type (DYS388=13) exists in Wales, where the frequency of haplogroup G is higher than in the rest of the British Isles.
Some Taylor Family Genes members in haplogroup G have started a mini-project
at Ancestry.com to assist each other.

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
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:
- For close matches, v3 = v1;
- For more distant matches v3 <= v1.
