The Basque people are notable for possessing the world's highest frequency of type O and Rh negative blood. This unique genetic profile distinguishes them significantly from other populations globally.
Unique Blood Type Frequencies
The prevalence of specific blood types within the Basque population highlights a remarkable genetic distinction. Their blood type characteristics are:
- Highest Frequency of Type O Blood: A significantly large proportion of Basques have blood type O.
- Highest Frequency of Rh Negative Blood: Beyond blood group type, the Basque people also exhibit an unparalleled frequency of the Rh negative blood factor. This means a substantial number of individuals in the Basque population lack the RhD antigen on their red blood cells.
Genetic Distinction
This exceptional prevalence of type O and Rh negative blood types in the Basque people is largely attributed to their historical isolation. The Basques are a people who have maintained a distinct genetic heritage by historically not mingling extensively with outsiders. This genetic isolation has resulted in a relatively unadulterated gene pool, leading to the sustained high frequencies of these particular blood types over generations. Their linguistic and cultural uniqueness further supports the understanding of their distinct genetic lineage.
