You've been tested. You got your results back from Family Tree DNA. Now your results are posted on your project's Results Page. But what does all the information posted there mean? Here's a quick guide to reading your results posting on the WorldFamilies.net website:
Start with the column on the left. The heading is ID. Listed in the column below is a letter, followed by a dash, followed by a number. This is your code identity number. In order to maintain privacy, we issue each test participant a code identity number which consists of the first letter of the surname, followed by a number which is given in sequence as participants are tested. For example, the 16th person to be tested in the Teaff project would be T-16. (If your pedigree is on the Patriarch page, we will correlate it to the test result by placing your code identity number beside the pedigree.)
The second column is headed "Name" or "Earliest Known Ancestor". The preference here is to put your earliest known ancestor, to preserve your privacy, and also because that is very helpful to other researchers and the project administrator in determining lineages
. When you were given your "personal page" at FTDNA, you were given a page called "Setup Preferences". At the bottom of this page is a place for you to enter your "Most Distant Known Ancestor". If you posted your ancestor there, or if you posted your pedigree on our website, we have access to your earliest known ancestor and make every effort to put it on the Results page under "Name". If we do not have it, however, we will post your name, using only your initials as a way to shield your privacy.
The third column is "Haplo" for haplogroup. Your haplogroup is a grouping of similar "haplotypes" that show your deep ancestry. If you have had a SNP test done on your test sample, you have a confirmed haplogroup. In this case, your haplogroup is shown in green. If you have not been SNP tested, FTDNA may have made an estimate of your haplogroup bases on your 12/12 match to someone who has been SNP tested. In that case, the haplogroup will show in red. If there is a dash in this column, you have not been SNP tested and FTDNA has not been able to make an estimate.
For YDNA Haplogroup Descriptions and Information, take a look at Charles Kerchner's work: http://www.kerchner.com/haplogroups-ydna.htm
The remaining columns consist of headings of certain marker "addresses", for example 393, 390, 19, 391, 385a and 385b. These "addresses" are the places on the DNA strand where certain patterns can be found. The genetics lab identifies this address by its pattern, and then counts how many times that pattern repeats at that address. The number of repeats for each marker is the number that is your test result, and these numbers are placed in the appropriate column. For example, if the pattern at address 393 repeats 12 times on your DNA strand, your number at that marker is a 12. These numbers are important, because this will be how you determine if you "match" another test participant's results.
To evaluate your test results to see if you have a "match" with another test, take a look at the information given as part of our FAQ question "What determines a match?"http://worldfamilies.net/faqs.html#match
DNA testing is an exciting, and sometimes confusing, new genetic tool. Hope this guide helps you understand your results a little better!
