Bronze Age Bulgarian R1a-Z93

No, it really doesn't.

Everybody probably has common ancestors with a lot of these samples. It isn't going to show on default for most people and it barely shows for you.

On default I don't even match that J2b2 from Dalmatia that has the same haplogroup as me nor the Vucedol that is not too different autosomally. It is like this for most people with pretty much any ancient sample.

I am afraid you’re wrong. Almost no one matches ancient samples on that level. This is why the threshold is lowered to revealed distant shared ancestry. Higher thresholds can’t pissibly produce high hits. It will merely give 1-2cm on 1-5 SNPs. I haven’t seen anyone get high matches for ancient samples. Recombination events simply do not allow for that. And it’s all random. Whatever SNPs you had on your ancestry may have not been inherited.

For example. I didn’t match autosomal with someone who is paternally descended from a common ancestor. I match 0 cm with someone who is part of my founder clade. Does this now mean we don’t share a common forefather because of random recombination effects that occurs every generation? How many generations you think have passed?

I share no CM with some ancient R1a samples even at low thresholds. So no, low threshold doesn’t always produce any ancestral relation. And yes low thresholds do reveal links. You have some Anglo Saxon SNPs because Goths cut through the Byzantine world. No ones pure. We’re all a mixed bag buddy.

I did not say that no common segments mean no ancestry. I said that common segments on 200-400 gives valid results for possible ancestry or recent common ancestor. About the anglo-saxons they came from north germany and denmarkvwhile the goths after balkans went to italy and spain. If I really have common segments with them it goes back to a common proto-Indoeuropean ancestor. And this is what I mean 50 snps and 1 cm gives too broad results and all Europeans will share common segments among us with these filters.

What about 100 SNPS - 5 CM?

Largest segment = 5.4 cM

Total Half-Match segments (HIR) = 5.4 cM (0.150 Pct)
Estimated number of generations to MRCA = 7.7

1 shared segments found for this comparison.

297562 SNPs used for this comparison.

57.210 Pct SNPs are full identical

How did you find MRCA?

I don’t think you understood anything I just said but ok. You’re making a lot of things up. Lol. Read into generational recombination. It’s a random process. Genetics doesn’t work the way you assume.

No it doesnt mean you have recent common ancestor but whatever .... these samples lived like thousands of years ago. Sharing a recent common ancestor would be absolutely impossible. Most people I have seen who match on default only get 1 or 2 segments on defuault and these segments are below 10 and cM is low. Its like nothing. It literally means you are not recently related which makes a lot of sense, could mean you have some very distant ancestry but so does everyone I am pretty sure.




Any segment below 10 is really low .... if you get a lot of small segments below 10 and high cm it could mean you are distantly related. This usually only shows on 50 snp.


Amyway, I don't think I have Thracian ancestry nor do I mean to ruin your fun. Enjoy.

I was meaning recent common ancestor for him of course. I get low cm segments for this on 200-400 while I need a filter of 50 to get low common segments for others. I suppose it indicates a closer relationship.

I have also done the comparisons you mentioned above with similar results. This is why I said that no common segments found do not mean necessarily no possible ancestry. I have at my 23andme matches different percentages of common shared dna between two matches who are brothers. I do not expect to share common segments with all my ancestors but if I find common segment with an ancient kit it is possible to be my ancestor and as far as I know 200-400 filter is the standard for such a comparison. I hope now you understand what I mean.

I don't have MRCA result but I get this match on default SNP.

Segment threshold size will be adjusted dynamically between 200 and 400 SNPs
Minimum segment cM to be included in total = 1.0 cM
Mismatch-bunching Limit will be adjusted dynamically to 60 percent of the segment threshold size for any given segment.

Largest segment = 1.5 cM

Total Half-Match segments (HIR) = 1.5 cM (0.042 Pct)

1 shared segments found for this comparison.

273732 SNPs used for this comparison.

54.214 Pct SNPs are full identical
