Discussion of Irish genetics thread

Tidied up a bit & put in a couple of Counties provided on this thread for K15. Though only Cork has enough for an average.

It makes a lot of sense where they plot when you look at location.

I've looked at quite a few results now and there is definitely a lot of Dutch showing up in these results. What do people make of this? Their is a pull towards Dutch, West Scots, Norwegians. So much for the Irish being descended from the Basque or any Iberian population that appears to not be accurate at all.

I'm pretty sure that due to a combination of imprecision in the original saliva readings and imprecision in the GEDmatch methods, differences between northwestern Europeans are not being detected consistently, resulting in almost random Oracle results within that region. I've got more faith in this:

I think French, Irish, British and, to a lesser extent, Germanics are partly descended from post Ice Age Iberians, but that genetic drift since then has pretty much severed that connection (look at the map I put in Gooding's Iceland thread in the Autosomal DNA section to see how quick and strong the effect of genetic drift can be).

We are pretty much made of the same basal populations.

The Irish DNA Atlas study should be pretty comprehensive (8 great grandparents from the same area). We'll have to wait and see what that shows.

Also some of those people have tested with 23andMe and like myself come out overwhelmingly British&Irish in their AC.

Looking at these results I think the Irish appear fairly uniform and there appears to be a trend across all of Ireland to some similarity to Scots and Dutch on these calculators whether you are from north or south of the island. The Irish appear quite similar to their British neighbours and I can't see anything unusual popping up in the Irish DNA Atlas when it is released.

Anyone surprised with anything or anything more to add?

I'm going to look at a few more Gedmatch results and if anything unusual shows up I'll post but the results do appear to be typically North West European which is not a surprise.

Interesting how one of the individuals has a chunk of east med, but it seems that most or the majority at least don't have any.

These are my grandmother's AncestryDNA results. She is 3/4 Irish and 1/4 Scottish.

These are my grandmother's AncestryDNA results. She is 3/4 Irish and 1/4 Scottish.

Those are pretty much the reverse of my mum's results (she is 7/8 English, 1/8 Irish):

Great Britain: 73% (Typical native: 60%)
Ireland: 12% (Typical native: 95%)
West Europe: 8% (Typical native: 48%)
Scandinavia: 3% (Typical native: 84%)
Finland/NW Russia: 1% (Typical native: 99%)
Iberia: 1% (Typical native: 51%)

Why on all these tests are results for Irish so extreme? On 23andMe most Irish get over 90% and on FTDNA 100% and on the AncestryDNA the typical native Irish person gets 95%. No other nationality gets such overwhelming results except possibly the Finns.

Similar to my grandfather's results. He's half French-Canadian and half Irish.
