The specific connection between the ancient Jewish/Hebrew population and blood type AB primarily stems from a landmark 1970s anthropological study published in the American Journal of Physical Anthropology. [1]
The Study: Researchers performed ABO-typing on 55 well-preserved ancient skeletons unearthed from archaeological excavations in Jerusalem and Ein Gedi. [1]
The Findings: The tests revealed that these ancient populations had a notably high frequency of the AB blood group (~50%). [1]
Genetic Implications: This indicates that the ancient Levantine populations possessed high frequencies of both the \(I^{A}\) and \(I^{B}\) genes, and a significantly lower occurrence of the \(I^{O}\) (Type O) gene. [1]
2. Genetic Ancestry
If you have AB+ blood, your blood type is characterized by the presence of both A and B antigens on your red blood cells (making you Type AB) and the presence of the Rhesus (Rh) factor (making you positive). [1, 2, 3, 4, 5]
Modern genetics has revealed deep, unbroken genetic threads linking contemporary Jewish and Arabic-speaking populations in the Levant directly back to Bronze Age inhabitants (such as the Canaanites). [1]
Blood types A and B represent ancient global migrations and adaptations over thousands of years, with AB being the youngest and rarest blood group globally (occurring in less than 4% to 5% of the general population)
Pregnancy: Because an AB+ mother or fetus naturally expresses the Rh factor, the dangerous incompatibility issues that cause hemolytic disease of the fetus/newborn (Rh incompatibility) do not apply to the
