Gene frequencies of the esterase D system were estimated in a sample of 1,392 unrelated adults living in Copenhagen; the results were EsD1 = 0.896 and EsD2 = 0.104. No genetic linkage could be demonstrated between this system and a series of autosomal makers.
在对居住在哥本哈根的1392名无亲缘关系的成年人样本进行检测后，估算出酯酶D系统的基因频率；结果为EsD1 = 0.896，EsD2 = 0.104。此系统与一系列常染色体标记之间未发现基因连锁现象。
