Are phenotypes more related to YDNA and MTDNA than they are to autosomal DNA?

IMHO, it’s autosomally.

My phenotype only pass in part of West Asia and part of South East Europe.

My paternal haplogroup is common among the Irish, but I have a Spanish phenotype

I was cheated and want a refund, fuck!!!!

That is why African-Americans in the US can have YDNA and MTDNA from Europeans and not look European. It is from your parents and grandparents that you inherit physical characteristics such as hair and eye colour and shape of nose, height etc. None of these traits are inherited via your ydna or mtdna. Ydna for example is only passed down from father to son and not to females. I'd like to see the explanation of your friend on how ydna or mtdna would be responsible for phenotype?

Autosomal dna is responsible for the majority of your dna and that is why it is used in deciphering such things as your ethnicity or what populations you hail from.

You could be right. This explains why do blue eyes and pale skin seem to dominate in Ireland where you are from for example, while it doesn’t at all in Iberia. Although as a whole the R1b Y-DNA haplogroup is dominant in both areas.

Ha!ha!ha! What are you talking about? There are African - Americans that dark. Have you been to America before?

Do you know Michael Jordan?

The R1b in Ireland is majority L21 and in Iberia it is DF27. Also the Irish are much higher in Steppe ancestry than the Spanish. Also all R1b came to those countries from further east and it would depend on the people that they mixed with on their road to their final destinations. Ydna is only good for tracking ancient migrations. The populations you are similar to autosomally are the ones you cluster with. All R1b at any rate came to Europe via the Corded Ware. They also brought R1a with them. Whatever happened in Corded Ware men that carried R1b ended up more West. All these groups be they Corded Ware or Bell Beaker were very tribal and patriarchal. It is why one ydna will win out over another. The most powerful male gets to have the most women.

Where did L21 come from in Iberians who have it?

It came from various sources. Among those who brought the DF27 to Iberia from Southern France, there were probably individuals who were L21 as well. As well as the Britons who were fleeing Anglo - Saxon invasion in the 5th century, the majority settled in Brittany, France and a minority settled in NW Spain. The same area of Iberia with a high frequency of L21.

I think it came later than the Bronze Age. When Beakers came to Iberia they were were DF27 and all the ancient Bell Beakers tested in Britain were L21. The studies done so far were focusing on the Bronze Age and late Bronze Age so hopefully more studies will come out giving more clarity on some of these questions. I'm very interested in why Beakers in different areas had different dominant clades. I can see how this could happen but it is very interesting and there needs to be more studies done.
