A total of more than 800 placentae from six different population groups have been examined for electrophoretic variation in 13 enzyme systems. Whilst, in many instances, the phenotype designation is presumptive, having been arrived at after critical visual comparison with illustrations in the literature, a number of new alleles have been reported here and further population genetic data have been presented. Two new alleles, MPI3 and MPI4 are described in the mannose phosphate isomerase system the former in both the Port Moresby sample and in the Chinese, whilst the latter was restricted to the Chinese samples. Also, the New Guinea MDHs 3-1 phenotype has been detected for the first time in placentae. In addition, a new allele in the aconitase system, ACONs8 has been described in the Chinese samples.
对来自六个不同人群组的总共800多个胎盘进行了检测，以研究13种酶系统的电泳变异。虽然在许多情况下，表型命名是推测性的，是在与文献中的插图进行严格的视觉比较后得出的，但本文报道了一些新的等位基因，并提供了更多的群体遗传学数据。在磷酸甘露糖异构酶系统中描述了两个新等位基因，MPI3和MPI4，前者在莫尔斯比港样本和中国人中均有发现，而后者仅在中国人样本中出现。此外，首次在胎盘中检测到新几内亚苹果酸脱氢酶3-1表型。此外，在中国样本中描述了乌头酸酶系统中的一个新等位基因ACONs8。
