    1. Re: [DNA] Y-DNA test - which one?
    2. Barbara Ryan via
    3. Since I am female, I only received my maternal haplogroup (H7) from 23andMe. However, in looking at the paternal haplogroups of my 486 relatives who have one, 271 have a paternal haplogroup starting with R1b1b2. My father's grandfather is from Ireland. Is it likely that my father (deceased) had this haplogroup?

    3. Yes, sorry...I misread your post and thought that your father had done 23andMe...in which case they assign some sort of yDNA "haplogroup" for paternal line (if you are a male) and mtDNA haplogroup for your maternal line. But it's not the same yDNA test that you would get by testing STR markers at FamilyTreeDNA. I've found all my 23andMe predicted haplgroups to be consistent with FT DNA...at least in a gross sense.

    2. jlerch1 via
    3. You didn't mention:  Did the surname you were searching come from a genealogical trail with no father/son connections between that ancestor and you.  IOW you got your X from your mom as did all the putative intermediaries.  So if it is significant, not only is the trail correct but because that person got his/her surname from his/her father, the terminal person would be that 1st person in the trail with that surname.

I looked up one of my family surnames that were all born in the same country. Then picked out those whose details sounded familiar as well as those surnames who came from the same or adjoining counties as mine. I then compared their results in the 3D Chromosome Browser. The results were not too dramatic,some of the matches were in the 5cms and 6cms range. One result though on the x-chromosome I thought might be significant, one block over 8cms. and another block over five, both with the same person. My query is would the x-chromosome really be significant and also due to the similar surname and geographical location would the other five to six cms. matches also have some relevance. David

    3. I would go with the 37 marker or 67 marker test at Ftdna, the 111 marker is often more than a person needs. If your paternal line comes out of Ireland or the UK go with the 67 marker but if the ancestry is from Eastern Europe there is a chance there would be few or no matches and 37 markers would be a good stating point.

Yes but it still means that if there was a 8cM ancestral segment and it gets cut into half the size (just an example, recombination is basically randomly happening) for the next generation it's still a small portion of our ancestors DNA.

    3. Barb, FTDNA is the only company now. Y-DNA37 should be fine to determine which line you belong to in a surname project. Additional markers usually don't offer much, but there is no blanket statement. It depends in every case.You can always upgrade later, if needed. The current sale prices are very good. FTDNA usually has a summer sale, too. And often a guick flash sale at other time - sometimes for DNA Day.

    1. Re: [DNA] Small segment matches when the common ancestors are known
    2. Karla Huebner via
    3. Small segments are one of those instances where testing multiple known relatives is important. I often see where two (or more) have a fairly long segment but their close relative recombined to have 6.8 cM or something of the segment. I realize that not everyone has lots of known relatives available to test, but to the extent that I have done so, I've been able to mark a lot of relatively short segments as IBD because it is clear where recombination took place. That said, I don't go looking for short segments... life is too short for that. However, Genome Mate Pro shows me where the tested relatives are matching a given person, so I can see pretty quickly if two or four people have a big match and another has just a bit of it.

    2. Karla Huebner via
    3. You'd think the least they could do if they were going to double the price and then have a sale would be to make the sale price an opportunity for people to get one last test (or set of tests) purchased at the old price. Oh well.

    1. [DNA] P.S. RE: Y-DNA test - which one?
    2. Loretta Layman via
    3. I should have also said that 37 markers is a good starting point, but the savings are greater on the 67 and 111-marker tests, and you may need or want to upgrade at some point anyway. The year-end holiday sale is typically their best.

    3. You should go with FamilyTreeDNA (FTDNA) for a number of reasons, one of which is that they are having a sale now through December 31. The first thing you'll see on this page is Family Finder, which is their atDNA test. The Y-DNA tests on sale are below that ... https://www.familytreedna.com/products.aspx Loretta (Lynn) Layman -----Original Message----- From: genealogy-dna-bounces@rootsweb.com [mailto:genealogy-dna-bounces@rootsweb.com] On Behalf Of Barbara Ryan via Sent: Friday, December 04, 2015 8:40 AM To: GENEALOGY-DNA@rootsweb.com Subject: [DNA] Y-DNA test - which one?

    3. People in any R1b subclade from R-M269 on down should consider going to 111 Y STRs. R1b-M269 (actually R1b-P311's) expansion across Europe is now being documented by scientists as a fairly recent timeframe - the Bronze Age. This means that R1b people from Europe typically have STRs that follow along with the Super Western Atlantic Modal Haplotype and our tree looks more like a bush. We need more STRs to discern our haplotypes in matching systems and analysis. Please look at this excellent presentation by Dr. Maurice Gleeson at the November FTDNA conference. https://www.youtube.com/watch?v=rvyHY4R6DwE&feature=youtu.be He does a nice job of going through the ins and outs of SNPs and STRs in a real case surname-cluster study for R1b. He clearly points out that 111 STRs are needed and even that is not without vagaries. He's also quite entertaining! This video is well worth the watch and backing up and looking at some of the charts twice.
