REAL DNA test results of Chris596

[Chris596]

The previous ancestry report was a weak attempt by Myheritage to shake up my identity by giving me “false” results. Thanks to some kind-hearted and helpful members, who saw right through the trick, I was able to find out my true origins, at least I got much more realistic data. Please share your thoughts in the comments down below. I think this is definitely worth a new thread

Some interesting things:

- The Jewish ancestry completely disappeared (I didn't find any Jews in the birth certificates)
- I'm still mostly Balkanite but this is obvious considering my ancestry :) (And I'm happy about it)
-The North and West European component is higher and I got more than 10% East European
-And the last one, the most unique component is what really suggests my roots and my ethnicity, is now present here

Maybe the legend is true and Myheritage really likes to give people free Jewish ancestry and tries to shake up their identity? :rolleyes: :rolleyes: :rolleyes:

They are not false necessarily, as I'm sure that everything that they showed is there, but because the new generation of tests don't look at a lot of SNPs, some signals slip right through the cracks.
After imputation the results of my family now include more East Asian and a stronger North Atlantic-shift, which is how mine always used to be. Since I tested on the old generation of 23andme and LivingDNA, imputation didn't change anything for me.

Regarding Jewish ancestry, there is an easy way to check that.
Go to DNA -> Overview -> Ethnicities.
Sum the number of matches. Then divide the matches with Ashkenazi Jewish by the sum of matches and multiply the result by 100%.

My mom gets 1.6%, my dad 8.9%. My brother and I get 7.5% and 8.7% respectively. From this, it is clear to me, that there is an Ashkenazi Jewish signal on my dad's side, even though it's so faint that it doesn't get detected on MyHeritage. However, on 23andme I received 0.3% Ashkenazi, which has been there since 2015 and also remains at 0.3% irrespective of the confidence levels. It must be real, but very distant.

I got 1.6% based on my previous DNA test results. But this ancestry report completely lacks the Ashkenazi Jewish so I can't divide anything. It's interesting nonetheless.

Oh and something really funny, now at the DNA matches my relative from Hungary still pops up and now our DNA is almost 2% (1.9%) identical.

None of us in the family have Ashkenazi Jewish as a component, so you are probably looking at the wrong thing, because your matches should be unchanged.

Hopefully this is helpful.

(168/2004) * 100% = 8.38% ?

Yep, you probably have a tiny amount of Jewish ancestry based on that. By tiny I mean on microscopic levels, less than 0.5% as in my case, but which is detected because of how inbred Jewish people are.

I don't get it. You did another test or something?

Short answer: No

Long answer: Many members suggested me to convert my DNA file to 23andme V3 version, which is (presumably) ,,more realistic'' ? So I did it and uploaded the file once again to Myheritage and this is what I got. My SNP count is more than doubled.

But how is that possible? Isn't SNP count determined by the amount of genome segments/locations that the lab analyzed?

This is a good question. Maybe other members like Kaspias can give you a better answer.

There is a method in the genetic calculation which can be called as "pipeline." It means, even the companies themselves are not testing all of such SNPs but test a base amount of it then run a prediction algorithm by using that stem. VCF conversion does the exactly same process. It is called prediction because the output will not be your actual SNP's yet it will give your actual statistical data while comparing yourself against components. The process is done this conversion is extending the read-capacity of the file, because the actual raw file is limited according to the needs of algorithm which runs in the admixture breakdown. But we want to use it with third-party tools too, and this limitation reduces the accuracy of measurements being done by other tools.

See how it is accurate in statistical results(Gedmatch etc.)

Superkit includes 4 raw data:

On the other hand, you can't use this file while predicting your y-dna, mt-dna etc. Because the SNP's will be replaced with predicted ones which will cause wrong assumptions.

By deduction from what you had analysed in your genome, which is a hit or miss, but they are confident in it for Europeans.

Thanks Kaspias! So overall, if anything, this ancestry report is more accurate, right? See how much East European I've got? (probably from my Hungarian side). And also, I'm curious what's going to be in the next big Myheritage update with the regions and everything.

It should be more accurate because data you provided has more coverage. But this kind of result given by companies is always a grain of salt to me.

I'm also curious about MH and FTDNA updates but if they keep using modern populations(such as Turkish for Anatolia, Serbian for Balkan etc.) they will not be advancing in what they do.

Could you redirect me to the website or tool you used to do the 23andme file conversion?

[Dr_Maul]

Cool result, should I bother with converting it? (I tested 23andMe last month, idk if it’s V3 or the ‘good’ one or not)

Thanks! Well, it's your choice but I mean it made a huge difference in my case, as you can see it :D For some reason the tutorial was removed from the internet 3 days ago, but I can send you the download link at least.
