Rh- frequencies in Basques – French: 24%. Spanish: 28%, Chilean: 33%

There are different reasons why some studies don’t hold water.

Especially the ones claiming to represent national data.

Nations are man-made.

Tribes are more organic.

A prime example:

What is the frequency of Rh negatives in Chile?

Do you know?

Se estima que en Chile el 10% de la población tiene sangre Rh Negativo

Sorry… this one is in English:

It is estimated that in Chile 10% of the population has Rh Negative blood

Some studies on Chile show frequencies below 1%, others more than 30%.

It is what happens when the highest Rh- population mixes with the lowest Rh- population.

Back to the Basques:

I like this study:

Blood Group Interaction and the World Distribution of the ABO Gene p2 and the Rh Gene r (cde)

I am pretty sure you could probably find me a regional study with Rh- results as high as 44%, but I am not in the business of showing records, so for now, this conservative study suits just fine.

A 0.532 cde gene frequency for mostly Spain comes to 28.3024% Rh negatives among its Basque population.

Biarritz on the French side shows significantly lower frequencies with cde at 0.493 coming to 24.3049%.

This study shows also between 24 and 28% (more or less) frequencies, so I will go with that number.

Rh+ frequencies in ancient Europe

Remember?

Basques are somewhat isolated, more in Spain than France, but not THAT isolated.

The Rh- frequencies go down continuously.

Yes, I have see studies close to 40% and others as “low” as 21%.

To make a long story short:

Among French Basques, around 24% are Rh- and around Spanish Basques 28%.

As for the Chilean Basques, the 33% Rh- frequencies from above listed study may seem surprising to some, but not me.
