A lot has been happening with Frazer YDNA recently. In January, Rick’s new BigY 700 came in. Rodney upgraded his BigY 500 to a BigY 700. This came in at about the same time as Rick’s results. At the beginning of February, the new Frazier BigY 700 results started to come in. However, there are still a few loose ends.
- I assume that there will be a manual review of the Frazier results by FTDNA
- Rodney and Jonathan from the James Frazer Line both have pending Y-HAP-Backbone tests ordered by FTDNA. These were apparently ordered to fill in gaps from their BigY testing.
What Gaps Do Rodney and Jonathan Have in Their BigY Testing?
This was discussed some in my Blog: Frazer YDNA Loose Ends and Private Variants. In that Blog, I looked at Private Variants. The conclusion of my review was that I thought that FT420438 and FT420010 should be added here:
Let’s see if that still makes sense now that the Frazier results are in. In my last Blog on the Frazier results, I came to the conclusion that these SNPs should be added:
The good news is that in both my analyses, I had FT420010 in the R-YP6489 Block. The bad news is that in my first Blog, I had FT20438 in that Block and not FT426078. In my more recent Blog, I had FT426078 in the R-YP6489 Block and not FT20438. Confusing, isn’t it? My assumption is that FT420010 does indeed belong with R-YP6489. I will just check Frazier to make sure:
Position #5987829 is the position for the SNP FT420010:
Here is a chart I just made to compare the testing results between the five testers:
This shows that for FT420010, the three people who had the BigY 700 tested positive. Jonathan and Paul had the BigY 500 and their tests were inconclusive. That means that there were not enough reads or not enough positive reads. All this to say that FT420010 checks out. What I don’t know is if it belongs even further upstream – say to where the Stuarts are on the Block Tree:
This is a SNP that I suggested should go in the area of YP6489. Here is the position number:
Did Frazier test positive for this SNP? Here are the six Private Variants for Frazier:
Frazier did have Position number 4056256.
Paul’s results were inconclusive for this position number on his YDNA test:
This is where my comparison chart should come in handy:
Next, I fill in the other boxes:
The unfortunate part about this is that Rick’s BigY 700 which should have had more covereage than the BigY 500 tests, did not test for Position #4056256. However, based on Rodney and the Frazier tester testing positive, I think that FT426078 will be added to the Frazer/Frazier group of R-YP6489.
Prior to the Frazier BigY test results, I had suggested that FT420438 be added to the area of R-YP6489. Let’s see if that still makes sense.
Here is a summary of what I had for my earlier Blog:
At that time Frazier was not yet tested. What are the Frazier results for this position? Again, these are the six Private Frazier Variants:
I see nothing in that list starting with 118… Next, I’ll look at Frazier’s csv file:
It was worthwhile downloading the large Frazier csv file, because the results are interesting. This shows that Frazier has no mutation at this reference. If the Reference and Genotype are the same, that means that there was no mutation – unlike Rodney and Rick:
In testing YDNA, a negative result is as important as a positive one. That means that FT420438 is a defining SNP for the Roscommon Frazer group along with the three others they already have.
A Predicted Frazer/Frazier Block Tree
Here is what this appears to show:
This view is from the perspective of the new Frazier tester who would be in the right column. Two of his six Frazier Private Variants will go up to R-YP6489 reducing the Frazier Private Variants to four. Rodney will have a reduction of four in his Private Variants. That will likely reduce the average Private Variants of Rodney and Jonathan from 4 to two. Rick will have a reduction of two Private Variants. That should reduce Rick and Paul’s Group from three Private Variants to two.
More on the Frazer/Frazier Block Tree
It seems like this area of the Tree where the red arrow is pointing is important:
This must be the are where the two Frazer/Frazier branches divided from each other. However when was this date? From the Rodney/Jonathan Line there should be 8 SNPs below the point where I show the arrow. On the Rick/Paul Line there should be 9 SNPs. On the Frazier Branch there should be a mere 4 SNPs if my analysis is correct. The average Frazer Line is 8.5 SNPs long. I’ll average that with the Frazier Branch that has 4 Private Variants to get 6-1/4 SNPs. I’ve seen various number of years to apply to these SNPs. I’ll try 84. 84 times 6.25 is 525 years. That brings us back to about the year 1495. That is a little earlier than my previous guess of 1600. If I apply the 84 years to the remaining 5 SNPs that I have in R-YP6489 that is another 420 years. That brings us back to the year 1075 when we are bumping up against the Stuarts and possibly Grant. That would make sense as it would help if this date was around the time (or before) of the adoption of surnames.
So where I have the arrow pointed should be about 1075. The next break in the blocks should be around 1495. The next break in the blocks on the left two Frazer lines should be around 1690 which is the date we are guessing that Archibald Frazer, the father of the James and Archibald Lines was born. The number of 84 per SNP breaks down between 1495 and 1690 as there would be four SNPs during this period. This is a little less than 50 years per SNP. As the 84 years should be an average, it could be that there were a lot of SNPs forming during this period of time on the Frazer Line. It seems like the Frazier Line was helpful here as this line perhaps had fewer SNPs forming between 1495 and the present. At an estimated 4 Private Variants over about 525 years, that is one SNP about every 131 years. The same effect can be seen in the Stuart and Grant Lines, though this could be partly due to the Stuarts taking the BigY 700 and Grant taking the BigY 500 test.
Rodney and Jonathan’s Y-HAP-Backbone Tests
I’m still not sure why FTDNA ordered Y-HAP-Backbone Tests for Rodney and Jonathan.
Jonathan was missing some information on these three positions. However, Jonathan had good result for these three positions. It could be that there were some discrepancies between Frazer/Frazier and Stuart/Grant with other SNPs that I don’t know about that FTDNA wanted to clear up.
Summary and Conclusions
- In my previous two Blogs, I came to some conclusions as to where some of the Private Variants should end up for the five Frazer/Frazier testers. However, in this Blog I put that information together to give a fuller picture.
- In order for there to be a new SNP that is unique to the Frazers of Roscommon, it has to be positive for that group, but also negative for the Frazier tester. That was the case for FT420438. That would also be true for the existing three SNPs in the Roscommon Ireland Frazerr Block of FT421618. I didn’t check FTDNA’s work for the existing three SNPs in the Block, but I assume that they were right.
- I showed where I think that Frazer/Frazier Block Tree will end up once FTDNA has finished its manual review. I also did some guesswork as to the dates at some important junctures in the Block Tree.
- The Stuarts and Frazers seem to go their separate ways around the year 1075
- The Frazer and Frazier lines seem to separate around 1495.
- I’m still curious as to why FTDNA ordered Y-HAP-Backbone tests for Rodney and Jonathan.
