The marker
values were given special weightings
to de-emphasize proportionally those markers that
show the most
diversity of values and that experience mutations more
frequently. This procedure has been
been used in
published studies.

The Family Tree DNA categorization of G
samples
There exists
a version of the listing of G categories provided by Family Tree
DNA. This is according to
the lab's standard format which means
many limitations in the display. Perhaps the most serious limitation
involves very short titles for categories. Using the category names
listed above on this page you should be able
to match the categories to the ones at Family Tree. Sometimes the
Family Tree category titles use group numbers
rather than a descriptive
title, and the categories at Family Tree are subdivided less for large
groups than above.
The categorization at Family Tree DNA is not
automatic. Each sample has been individually placed according
to a
category.
The advantages of the Family Tree listing is that samples all
are on the same page. Haplogroup entries in green
represent categories confirmed by SNP testing. Red
entries for this catergory are only predicted by the lab. In my
categorizations, all names pertaining to a specific SNP have
the same background color no matter how many
subgroups are
encompassed by a particular SNP.
Some of the men
listed are fully confirmed to be in the SNP category listed. Others,
especially those
with only 12 markers as the only test result, are only
predicted to be in that category.
Link to the Family Tree version of G categorization in
wide screen format. This may not function during
peak times of usage
and may load slowly (or not at all) over slow connections.
A different version of the Family Tree DNA display
exists. It is more cumbersome due to using a window
within a window,
but it has a GoogleMap showing the ancestral origins of
members which are
generally correct but may have some
guesses. Separate map displays are available for G categories using
the
menu at top left. You will have to zoom in to see any
details. About 86% of project members have provided
locations of their
oldest known ancestor. It is recommended that you NOT use the wide screen
format option on
this page as there is a distinct possibility the screen will
not have enough memory.
Thanks to Peter Christy, Bill
Van Hemert, Ted Kandell, Whit Athey and others who have provided research
or
participant recruitment. All surnamed samples are from persons who have
joined the Haplogroup G
project at Family Tree DNA or public databases or are
from persons not in public databases
who have given specific permission for
display of their data. Anyone desiring to have their samples
removed,
need only request this. Any errors are my sole responsibility, and I will
willingly change
anything that is not correct.
