Re: Match on block tree but not listed as Big Y Match

 

开云体育

Hi all - apparently FTDNA have taken away the average number of private variants from each haplogroup on the Block Tree. The teal-coloured blocks that used to denote these have been replaced throughout by hashed-out boxes.


Mary - happy to look into your kits, but I'll need the kit numbers - feel free to send me them privately. The "x" either means there are no mis-matching variants (say, if you have a match within your immediate family) or that data is absent due to some error. If you've already written to FTDNA, they'll be able to give you a more authoritative answer than I can.


Cheers,


Iain.


Re: Match on block tree but not listed as Big Y Match

 

Hi, all!

Thank you, Iain, for your reply and suggestions - and for your offer to look at the kit.??

Both kits are old - a few years old.??

There are no Big Y matches at all, which makes it easy to tell that the match on the Block Tree isn't in the match list.

I took 颁颈补谤á苍's suggestion, and?I have a query in to FTDNA.

I appreciate all the suggestions and help from this group's members.??

Side question:? when I click on the block in the Block Tree to get the Branch Information Card, why does an X show up for one of the two matches below under the non matching variants column?? It's filled in for one match, but has an X for the other.? This is a different kit than the one I was asking about.? The detail for that kit, which has only one Block Tree match, also has an X in that column.? So I looked at another kit - below - to see what usually shows up there, but I don't know what the X means for one of the two matches.

Thank you!

Hi Mary,


If the match isn't shown on your list of BigY match, you can't check the number of mis-matching variants.


Overall, this is an issue that doesn't look like it should occur, but which we've seen before and was then (IIRC) related to a hiccup in quality control whereby parts of results are released either piecemeal or prematurely. If this is a new match, it could be that the test has had a haplogroup assigned, but that the matching algorithm has not yet been run - your best bet then is to wait a little while for the database to be recomputed (this may be an overnight or weekend job).


If they don't show up by then or disappear from your Block Tree, you'd need to contact FTDNA for the specifics. Before you do, you might want to do the usual sanity checks - make sure their name hasn't been abbreviated to fit on the Block Tree, that they're not simply on a second page of results, and that all the pages have recently been refreshed. I can have a look myself if you like, though I'm not sure of the kit number.

Re: Match on block tree but not listed as Big Y Match

 

Hi, all!

Thank you for your reply, John!? What I find conflicting is that the match shows up - by name - in the block tree, but isn't listed in the Big Y matches.? I would think that if they are mismatched on more than 30 variants the match wouldn't show up in the block tree, either.??

Questions:
  • There are only an average of 4 private variants between the tester and the match.? Is there a correlation between private variants for two matches and the total number of variants on which the two testers don't match?? Four private variants seems like a pretty low number, which makes me question whether or not the two have different results on more than 30 locations.

  • How can I double check how many variants the two have a mismatch on, please?? Three csv files can be downloaded for the Big Y results - Derived SNPs, Ancestral SNPs and No Call SNPs.? I would think the way to determine how many variants the two don't match on would be to compare the Derived SNPs files - and however many SNPs have a different value would tell me whether they are a mismatch on more, or less, than 30.? Is that correct?

Thank you!

Mary

Hello Mary

Big Y matches are restricted to those with 30 or less non matching variants.

Blocktree matches start with Y37/67/111 matches that do not make the cut, followed by the Big Y matches.

Re: Match on block tree but not listed as Big Y Match

 

Hi!

Thank you for your response, 颁颈补谤á苍 and?Raymond!? The match shows up in the list of STR matches, and has provided a family tree and earliest known ancestor.? And they show up on the block tree.? (And they are a member of the surname group) Is it possible for a match to opt in to sharing that information, but not sharing that they are a Big Y-700 match (and sharing the information for matching, non-matching and private variants)?? Can a match piecemeal what they share in that fashion?? I'm thinking I should take 颁颈补谤á苍'蝉?advice and email FTDNA to make sure everything is reflected properly on the account.

Mary?

Re: Ancient connections

Hi Kevin,


Effectively this is saying what portion of the FTDNA database is in the haplogroup you share with this ancient individual. In this case, that haplogroup is R-FGC13326, so one in every 605 customers (for a total of 424 out of about a quarter-million customers) is FGC13326+.


This is effectively a way of showing how significant this result is to your ancestry but, really, there are probably more important factors to look at. Altheim 1 is from very early medieval Bavaria, so any connection you have to this individual has to pass the 2000 years between the early medieval period and the ancestor of R-FGC13326 to have any relevance to your ancestral line. We can't easily piece together that 2000 years, so Altheim 1 only has very little relevance to the history of R-FGC13326 as we can trace it today.


Cheers,


Iain.


Re: Ancient connections

 

Hello Kevin

1 in 605 is a 0.165% chance.
ie if we start with the 256,557 Modern results, and divide that by the 424 closely related men, we get a 1 in 605 chance
To check 605 x 424 = 256,520 and - 256,557 = 37 rounding error.

Kind regards
John

Re: Big Y Lifetime Analysis: The Myth of the Manual Review

 

Thank you Debbie.
Interestingly, my branch is coded BY... even I testes Y-700 directly. Maybe because I split from a Y-500 tester?
"Y-SNPs discovered from the Big Y-500 will have the prefix BY followed by a number, e.g., BY147, BY592.Y-SNPs discovered from the Big Y-700 will have the prefix FT (or FTA, FTB, FTC, FTD, etc.) followed by a number, e.g., FT385, FT62."

I’ve just logged into my FTDNA account and I can access my Family Finder matches without any problem. The message is still displayed that we can’t download the match list and the segment data.

Geni.com does at least have the advantage over MyHeritage in that there is no limit to the number of people you can have in your tree with a free account.

You can also transfer your FTDNA DNA results to Geni.com though, given that they only seem to accept transfers from FTDNA, there seems to be nothing to be gained from doing this:

I am not even able to pull up matches currently. My father and mother each have over 4000 family finder matches. I work on a family at a time (currently trying to sort out the Jennens/Jennings family who had several children marry into the Maupin family) and I can not even pull up matches.

I will probably go to Geni.com who does attach both Y and MT to the direct lines making it easier to follow the line for potential matches. You can also lock a person's profile to prevent unapproved matches.


Re: FTDNA Administrators Conference 2023

 

My view is the FTDNA tree has a serious deficiency in the sophistication department. In my experience, using the MyHeritage tree is slightly better with more bells and whistles, but my main beef is I don’t like the 250 threshold for free members. I would say Ancestry stepped up their game with their tree functions and enjoy using it. Every few months I will cancel my subscription with Ancestry and wait until they start emailing me with hints, etc., then re-subscribe. Seems to work for me doing it that way. I haven’t considered Geni and may experiment with it over the coming weeks. I tend to use Ancestry and Familysearch to work on individual lineages and post those to my main tree at Familysearch and WikiTree. I’m intrigued by Geni though.?
