TBH I will always believe the Irish and Basques are super close to each other. Autosomal is not the way to tell who is close to each other. They both have high amount of R1b and at some point R1b were their own homogenous people. Irish and Basque are closest to the old R1b homogenous group. No way they are closer to Nordics. Nordics aren't related at all, they had no R1b until some of them mixed with other groups.

The Y chromosome is one small part of the genetic picture and not very significant on its own, so autosomal is the way to tell proximity between populations. The Scottish Highlanders have very significant amounts of Scandinavian and German type DNA so until we know more we must assume the southern Irish are similar. The Welsh have about 7% Spanish, though.

Well, I disagree. R1b is not a small part of the genetic picture, rather autosomal is. Figure in some parts of Ireland almost everyone has the R1b Y-DNA. So, they are mostly that genetically. So I disagree about autosomal test being the way to determine who is closer.

2.173%

That's how small a part the Y-chromosome plays in the human genome.

And what if every single person in your family history has the R1b Y-DNA? Let's just assume that for a minute. How much would the person be then?

Your genome is made of 23 pairs of chromosomes, 22 autosomes and 1 allelosome.

The allelosome pair is XX in females, XY in males. The R1b haplogroup is a cluster of genes on aforesaid Y chromosome which is inherited exclusively from father to son, ergo every single person in my family cannot possess it by definition.

Autosomes represent the majority of one's genepool, 95.65% to be precise.

So even if everyone in my family had R1b Y-DNA going back centuries, it would not mean much?

It goes patrilineally, it was carried by your father, then his father and so on. It is irrelevant, for example, what kind of Y-DNA can be found in your maternal grandfather. If 2 populations are found to be carriers of the same Y-haplogroup, it means that they share a common patrilineal ancestor.

As Neon Knight said, the rest of the 22 chromosomes are more important in determinig genetic kinship, they contain all kind of data, proteic codification, genetic diseases potential, skin, hair and eye colour etc.

Here is a fairly recent study of maternal and paternal DNA in Ireland (Co. Mayo): http://voices.nationalgeographic.com...l-dna-results/

I stand corrected.
