Gedmatch

[loudam]

I was interested to see this post

I have a match on FTDNA with the largest segment 12CM's but on Gedmatch we don't show has a match, on lowering the thresholds to 500 SNP's and 1 CM's this is what I get

If I lower the thresholds for the same 2 kits comparing to
300 SNP's and 3 CM's the match of 6.6 changes to 7.7 and the SNP's change too

Minimum threshold size to be included in total = 300 SNPs

So I'm a bit bemused with all of this now and wonder is FTDNA's 12 CM's right or Gedmatches 6 or 7 CM's right..

Here are one to one compare results for my wife and I at gedmatch.


Minimum threshold size to be included in total = 150 SNPs
Mismatch-bunching Limit = 75 SNPs
Minimum segment cM to be included in total = 1.5 cM
Largest segment = 5.3 cM
Total of segments > 1.5 cM = 663.4 cM
Total of 241 matching segments.

One of my cousin matches at gedmatch >total of segments > 1.5 cM = 621 cM with the largest segment 12.1cM.

I think that the K15 is a real gem of a calculator created by Davidski.

I am not surprised with my links to these ancient dna specimens.

A 7cM segment, 7000 years. 7 recombination events expected for 100 births. 25 years a generation. 7000 / 25 = 280 generations. Probability of a 7 cM segment to survive intact one generation is (100-7)/100 = 93%. Probability of a 7 cM segment to survive intact 280 generations is 0.93^280 ~= 1.5*10^-9, or about 1 in 668 million.

So, the 7 cM shared segments with the LBK cousin are highly probably IBS. The 7 cM limit has no special meaning here.

In my thinking it is absolutely certain that you and me had numerous common ancestors (most of them via numerous routes) 7000 thousand years ago.

The Clovis(F999919)one to many compare matches are from 7>95cMs. It is amazing how this autosomal dna is passed on.

Cool. My all-Finnish 4th cousin is at 11 cM / 5.2 gen to Loshbour.

Why you and me are clearly more related to Loshbour than RISE98 is? RISE98 is not an in-betweener.

LBK F999916 has 1,500 matches above 7cMs. Rise 98 F999941 has 192 matches above 7cMs. So having a 7cMs matching segment with the LBK can mean that we are linked to a 7,000 year old cousin.

[192971]

I entered Lochsbour's kit number F999918 at gedmatch in the one to many compare and there are 1479 matches above 7cMs.

Strange. I would have expected continuity via ancient Scandinavia.

These results show that I have a lot of matching segments with Loschbour and the LBK woman so the autosomal dna of the Isles should be from 2,000-10,000 ybp and not 2,000-4,000

F999916 (LBK, Stuttgart, 7ky) and me:

F999918 (Loschbour, Lux., 8ky) and me:

So, the similar numbers show that Finnish autosomal DNA should be from 2,000-10,000 ybp and not 2,000-4,000. Also, the Isles and Finnish autosomal seem similar in this respect.
