Genetic DNA News

I have not included much DNA news lately... so, I have quite a bit to add today! First here is a listing of the major DNA laboratories:
http://freepages.genealogy.rootsweb.ancestry.com/~bonsteinandgilpin/dna/ydnaco.htm Company Contact Information Below: Family Tree DNA FTDNA - http://www.ftdna.com/ Relative Genetics RG - http://www.relativegenetics.com/relativegenetics/index.jsp DNA Heritage DNAH - http://www.dnaheritage.com/ EthnoAncestry EA or ET - http://www.ethnoancestry.com/ DNA TribesDNA-T - http://www.dnatribes.com/Sorenson Molecular Genealogy Foundation SMGF - http://smgf.org/ Oxford Ancestors OA - http://www.oxfordancestors.com/ GenTree gen tree http://www.genetree.com/ GeneBaseGB - http://www.genebase.com/ Trace Genetics Division of DNA Print TGD - http://www.tracegenetics.com/ Argus Bio mtDNA studies onlyAB - http://argusbio.com/ DNA Print - http://www.ancestrybydna.com/ DNAP

And here is a YDNA (YSTRs & others) COMPANY COMPARISON CHART used in genealogy studies of surname groups... these markers will give you your haplotype but only estimate your haplogroup.

The main labs all have 32 markers in common which can be considered the "basic 32" in genetic genealogy. Many people want to at least make sure they know which are the most commonly tested.

*I advise that it is best to aim to test at least these 32.*

The main 32 are of course (in groups of five so you can count them):-DYS385 (2 parts), 388, 389I and II; 390, 391, 392, 393, 394(19); 426, 437, 438, 439, 442; 447, 448, 449, 454, 455; 456, 458, 459 (2 parts), 460; H4, 464 (4 parts); YCAII (2 parts). All of the above, plus a lot more comes from Nelda L. Percival at the link at the beginning of this article on RootsWeb.

Here is a great chart comparing most of the above companies as to what markers are tested for each test: http://www.gendna.net/ydnacomp.htm You can print chart at 60% landscape to get the first 80 markers which will cover the most significant markers. If you know how to allow background to be printed from "Advanced" Internet options, check it so that you get the color lines to help you follow across the long chart.

Here are some tips that might be useful:
* Upload your results wherever you can so you can compare to the results of others and them with you. FamilyTreeDNA<http://www.familytreedna.com/Default.aspx?c=1> is good, as is Sorenson<http://www.smgf.org/ychromosome/search.jspx> and YBase<http://www.ybase.org/> just to mention a few. * There are many surname projects, if you are not a member of one then join one. Again search your testing organization site, other testing organization sites or Yahoo Groups. * There are also specific surname projects, here is a link to my paternal line discussion group and the analysis that is going on there. <http://www.personal.psu.edu/faculty/g/a/gah4/HamDNA/Results.html>

* Don't worry about the name just read the explanations. If you don't have something similar for your surname then start one. * Make sure you also have a paper record and it is published. The point is to use the genetic record to fill the gaps in the paper record. Rootsweb <http://wc.rootsweb.ancestry.com/> is good and is free. * Make your search systematic, starting with what you know. Find a distanced male line cousin and get them to do the test. Build the tree that links you and find the common male ancestor. Was there a mutation? Where did it happen? Then push it out further. * You must have at least the 37 marker test, anything less is just too general. * Does someone have a close match to you at 37, say one marker off? Find your common ancestor. What about two markers off? Find you common ancestor, he has to be back there somewhere. * Be prepared for surprises in particular the "non-paternal event." They really are very common. * Know your haplogroup; there is no point talking to anyone about ancestors who doesn't at least match that. [End "jhunter99" advice.]

And, finally, The FTDNA West Surname y-DNA Group #5 (of 28 groups) will hold our second DNA Family Reunion on 22-24 May 2009 in Poplar Bluff, Missouri. - Information compiled by JGWest
