The author carried out studies on 600 Bulgarians from the south Bulgaria (the town of Plovdiv) and 232 gypsies. There was gene frequency of AK1=0.9633 and AK2=0.0367 in the Bulgariana and respectively AK1=0.9784 and AK2=0.0216 in the gypsies as the differences between both populations were insignificant. All data, published up to now, were summarised connected with the examination of the Bulgarians for AK (1278) and the estimated mean values for gene frequencies were: AK1=0.9648 and =K2=0.0352). Gene frequencies of the Bulgarians, compared with other populations, revealed that they were in the ranges of the mean European values for gene frequencies and differed substantially from those of the nergos and some Asian nations (Japanese, Chinese). The theoretical probability for excluding fatherhood by means of the system of Ak for the Bulgarian was 3.28%.
作者对来自保加利亚南部（普罗夫迪夫镇）的600名保加利亚人和232名吉普赛人进行了研究。保加利亚人群中AK1的基因频率为0.9633，AK2的基因频率为0.0367；吉普赛人中AK1的基因频率分别为0.9784，AK2的基因频率为0.0216，两个群体之间的差异不显著。到目前为止发表的所有数据都与对保加利亚人进行的AK检测相关（1278例），估计的基因频率平均值为：AK1 = 0.9648，AK2 = 0.0352）。保加利亚人的基因频率与其他人群相比，表明他们处于欧洲基因频率的平均值范围内，与黑人和一些亚洲国家（日本人、中国人）的基因频率有很大差异。通过AK系统排除保加利亚人父权的理论概率为3.28%。
