Worldwide nations, regions and populations with highest frequencies of rh negative percentages

We are going to keep updating this post as new information is coming in.

So far, the nations with the highest rh negative frequencies are:

1) Poland

19.67%

2) Brazil

19.5%

3) Australia

19%

4) Spain

5) Ireland

Reports vary. Some low as 16%. Others 25% and above.

6) Slovakia

18%

Possibly:

Ethiopia

As there is only one official study discrediting a previously assumed lower frequency, more studies are required to verify the new results of around 20% rh negatives.

Territories and regions:

1) Basque Country


2) Scotland


3) Northern Ireland


4) Rhone Valley, Switzerland

The rh negative frequencies in several parts of the Rhone Valley have their "Walser" population at Basque-like percentages.

5) Catalonia

High in y-DNA R1b. Their famous son:


6) Sinai Peninsula


The Bedouins of the Sinai Peninsula are responsible for a high rh negative frequency in the region. Inbreeding is unfortunately high among them also contributing to a high percentage of hearing impairment.

7) Lower Silesia, Poland

21.1% rh negatives among women and 19.2% rh negatives among men.

8) Bunschoten-Spakenburg, Netherlands

This Dutch municipality with 20,000 inhabitants houses 25% rh negative people.

Populations:

Guanches of the Canary Islands


Descendants of Basques and Berbers.

Karaite Jews

Around 28% are rh negative

Populations standing out in comparison to neighbors:

Ainu people of Japan and Russia


Almost 10% are rh negative.

The Uyghurs of the Xinjiang Uyghur Autonomous Region of the People's Republic of China

Around 4.71% among them are rh negative which towers the Chinese average of less than 1%.

Possibly:

Parts of Atlas Mountain region in Morocco.

As all studies after Messerlin and Lohro (1951) have contradicted their findings of extremely high rh negative frequencies among the Ait Haddidu Berbers, more evidence is required to maintain the claim of theirs.

Ancient populations high in rh negative frequencies:

Yamnaya

Said to have been around 40% rh negative, they became the Celts in the West and the Scythians in the East. The famous Amazon women were Scythian. They are ancestors to the Persians and Aryans. Blue eyes and red hair may have originated within their direct ancestry in the same region.

Proto-Basques

We know their mtDNA and y-DNA make-up, but little about their blood type frequencies. They were invaded by the Proto-Celts 3,000 to 4,000 years ago and their original y-DNA almost completely replaced.
