View Full Version : Confusion over R0a

24-01-17, 04:03
I am not able to find much information about my 23andme results - citing R0a.. they told me it's rare in europe, but my Mother was Italian, her mother was Italian (Naples region), and her mother was Italian (so on and so forth for 100s of years that we know). Is this a common group for Italians? If so why doe 23andme say it is not, and is only found in europe vary rarely in Jewish populations (once again none in my known history).

Also I should add, every time I look at maps and breakdowns I never see R0a or the aka pre-hv - is there something else this is called? Sorry for the double post.

Check out my spreadsheet of Haplogroup Frequencies in Europe: mHG Frequencies (https://docs.google.com/spreadsheets/d/1sUEn8VzWv-48bCXQHaOSrFqLmdaewuc4jiiBipNtjls/edit#gid=0)

R0a is very rare in Europe including Italy. But it probably exists in every part of Europe. And its prescence can't be explained by recent Middle Eastern immigration like the migration of Jews. 23andme is wrong about R0a in Europe being derived from Jews.

Here's a summary of R0a frequencies outside of Europe. R0a peaks in Arabia and Egypt at 10-20%. The rest of the Near East(Syria, Lebanon, Turkey) has about 5% R0a. R0a reaches above 1% in all of the Middle East and even has a strong presence in India and Morocco.

Ancient DNA from the Levant(Isreal, Jordan) show R0a has been there for at least 10,000 years. R0a can safetley be called a Western Asian or at least Middle Eastern haplogroup. Its existence in Europe might have many different sources. My guess is most derives from a mysterious Near Eastern migration to Southern Europe which occurred in an unknown date after 3000 BC. These mysterious migrations no one knows a lot about yet affected Southern Italy the most. That could be why 1% of Southern Italians in my spreadsheet have R0a and why you have it.

Your mtDNA is one of the rarest in Italy. Overall 1% of R0 on Boattini et al and less than 1% on Sarno et al for Southern Italy and Sicily of R0 (3 case on 313 samples) ;)
Rare and weird

ROa, or at least RO has been found in Iron Age Catalonia and Denmark and in Magdalenian Europe.

We also have it in far older periods, in Magdalenian Spain. No need to limit its arrival necessarily to periods after 3000 BC or to Italy.

I have no idea why 23andme would label it as necessarily "Jewish" in Europe. Very odd.

From Geno 2.0

"Branch: R0
Age: About 41,000 Years Ago

Location of Origin: West Asia

Some individuals moved across West Asia into Central Asia and then the Indus Valley. Others moved south, heading back into the African homeland from where their ancestors had recently departed.

Later, members of this lineage moved north across the Caucasus Mountains and west across Anatolia into Europe. These were Cro-Magnon. Their arrival in Europe heralded the end of the era of the Neanderthals.

Today, members of this lineage are present around the Red Sea and widely throughout the region. While this genetic lineage is common in Ethiopia and Somalia, individuals from this group are present at highest frequency in Arabia. Those living in East Africa are the likely result of more recent migrations back into the continent.
