ABO‐typing of ancient skeletons from Israel

Sixty‐eight ancient skeletons, unearthed at Jerusalem and En Gedi and, according to the archeological data belonging to Jewish residents of these places from about 1,600 to 2,000 years ago, were ABO‐typed by means of the hemagglutination‐inhibition test. The blood groups of 13 skeletons were undiagnosable and the remaining 55 showed the following distribution: 30.91% A‐group, 14.54% B‐group, 50.91% AB‐group and 3.64% O‐group. According to these findings, the population to which these skeletons belonged must have had a high frequency of genesI^A andI^B, and a low occurrence of O blood group and its relatedI^O gene.
