The incidence of carriers of the Gd(-) gene and the Rh(+) and Rh(-) alleles was studied in 10 342 Bulgarian individuals living in 306 villages in 5 districts at different altitudes above the sea level. The results showed that the presence of the Gd(-) gene is considerably less frequent in Rh(-) than in Rh(+) individuals. In populations with a high frequency of G6PD deficiency the frequency of the Rh(-) allele is low.
对生活在海拔不同高度的5个地区306个村庄的10342名保加利亚人进行了研究,以确定Gd(-)基因携带者以及Rh(+)和Rh(-)等位基因的发生率。结果显示,Rh(-)个体中Gd(-)基因的出现频率明显低于Rh(+)个体。在葡萄糖-6-磷酸脱氢酶(G6PD)缺乏症高发人群中,Rh(-)等位基因的频率较低。
