Project Background

Dear Cook Group Participants,
The special "Y-DNA37+mtDNA for $119" has been extended!!!

From Max the Prez:
In the last few days we have received several e-mails from group administrators asking us to extend our "Unparalleled 50% Promotional Discount" Y-DNA37+mtDNA for $119 (the regular project price is $248 – a reduction of more than 50%!!), as many people are only now becoming aware of the promotion.

We have decided, therefore, to extend it until June 30th, 2009. Kits must be paid by July 7, 2009. In order for the most people take advantage of this promotion, we encourage you to post the following link in your family messages boards, blogs, and mail lists, as well as forward to people when they ask you where to place the order:

As always, that you for your continued support.

!!! ATTENTION PARTICIPANTS !!!!
DEC 8,2007
NEW RESULTS PAGE IS UP AND RUNNING.
Please go to:
http://www.worldfamilies.net/surnames/c/cook/results.html

A few things to remember:
a) Lineages = matches between 2 or more participants of 23/25 markers.
b) Lineages are by HAPLOGROUPS: in other words, you will see a LINEAGE 1 in the R1a haplo; a LINEAGE 1 in the I1a Haplo, & so forth.

A full explanation of the page is located at the bottom of the page.

Questions: email me at "cookdna[at]hotmail.com"
Jim Cooke

ALSO:
Please take a look at your ancestors on the Y-Results Page.
IS IT CORRECT?? COMPLETE???
If not, email me, OR:

Go to "MyFTDNA" [your personal results page];
Click on "User Preferences";
Scroll down to "Paternal Side";
Correct or update your data in the field;
Click on

The info you put in this field will display directly to the new page. Be Advised: the space in the field is limited, so be brief and abbreviate where possible.

Haplogroup & Allele Mutation Info:

Comments from FTDNA May 2003

It is obvious from our observation of 1000's of samples that some markers change or mutate at a faster rate than others. While that actual 'faster rate' has not yet been definitively calculated, not all markers should be treated the same for evaluation purposes. Markers 385a, 385b, 439, 458, 459a, 459b, 449, and 464a-d have shown a faster mutation rate then the average, and therefore these markers are very helpful at splitting lineages into sub sets, or branches, within your family tree. Explained another way, if you match exactly on all of the markers except for one or a few of the markers we have determined mutate more quickly, then despite the mutation this mismatch only slightly decreases the probability of two people in your surname group who match 11/12 or even 23/25 of not sharing a recent common ancestor. Note - On May 19, 2003 FTDNA reassigned the values for 464a, b, c, and d. Dropping each by one. Because of a change in Lab nomenclature. These results reflect those changes.
G
This lineage may have originated in India or Pakistan, and has dispersed into central Asia, Europe, and the Middle East. The G2 branch of this lineage (containing the P15 mutation) is found most often in the Europe and the Middle East.

R1a
The R1a lineage is believed to have originated in the Eurasian Steppes north of the Black and Caspian Seas. This lineage is believed to have originated in a population of the Korgan culture, known for the domestication of the horse (approximately 3000 B.C.E.). These people were also believed to be the first speakers of the Indo-European language group. This lineage is currently found in central and western Asia, India, and in Slavic populations of Eastern Europe.

R1b
Haplogroup R1b is the most common haplogroup in European populations. It is believed to have expanded throughout Europe as humans re-colonized after the last glacial maximum 10-12 thousand years ago. This lineage is also the haplogroup containing the Atlantic modal haplotype.

I
The I, I1, and I1a lineages are nearly completely restricted to northwestern Europe. These would most likely have been common within Viking populations. One lineage of this group extends down into central Europe.


I1b
This subgroup of Haplogroup I is found within the Balkans countries at it's greatest frequency and diversity. These countries probably harbored this subset of Haplogroup I as a refuge during the Last Glacial Maximum.


J2
This lineage originated in the northern portion of the Fertile Crescent where it later spread throughout central Asia, the Mediterranean, and south into India. As with other populations with Mediterranean ancestry this lineage is found within Jewish populations.


E3b
This haplogroup is believed to have evolved in the Middle East. It expanded into the Mediterranean during the Pleistocene Neolithic expansion. It is currently distributed around the Mediterranean, southern Europe, and in north and east Africa.


As additional information becomes available, members may be separated out into groups with identified common ancestors. In cases of ambiguous DNA results, we will depend in part on lineages supplied by the test subjects for determining how the groups should be constructed. All participants will be notified by email when new test results are posted.
