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 genesIA andIB, and a low occurrence of O blood group and its relatedIO gene.

68具遗骨出土自耶路撒冷和隐戈地（位于死海西南岸），根据考古学数据，这些犹太居民活动于1600到2000年前。经过血凝抑制试验，有13具遗骨无法测出，余下55具遗骨检测如下：
30.01的A型；14.54的B型，50.91的AB和3.64的O型。
根据这些发现，遗骨从属的人口（古犹太居民）必然拥有高频率的A、B等位基因，和偏低的O型血和O型等位基因。
