The Rh Negative Blog

Regions with highest rh negative percentages

People with red hair can be traced back to a single Y-chromosomal haplogroup: R1b.

The following regions worldwide are known to have unusually high percentages of rh negatives:
(In alphabetical order)

Al-Jouf Province of Saudi Arabia

Atlas Mountains, Morocco (to be verified)

Basque Country

Bunschoten-Spakenburg, Netherlands

Canary Islands

Catalonia

Chad (certain regions)

Chile (areas with high Basque populations)

Gambella, Ethiopia

Irish People

Karaite Jews of Iraq

Safien, Tenna and Versam in Rhone Valley, Switzerland

Scotland

Senegal (small, isolated tribe)

Sinai Peninsula

Yoruba populations of Nigeria

So how about on a national level?

On a national level, Australia appears to be the highest. Brazil also shows studies with similar numbers, but just like in other countries with high diversity, the overall numbers of the country will not likely add up to the likes of Australia’s.
