PGM3 polymorphism was studied in 301 placenta samples from the Negroid population of Northeastern Brazil. The following gene frequencies were encountered: PGM31 = 0.545 and PGM32 = 0.455. They lie between European and African gene frequencies. The prevalent Black and White admixture of Northeastern Brazil populations fits well with the observed gene frequencies. Two samples exhibited variant electrophoretic patterns.
对来自巴西东北部黑人种群的301份胎盘样本进行了PGM3多态性研究。发现以下基因频率：PGM31 = 0.545，PGM32 = 0.455。它们介于欧洲人和非洲人的基因频率之间。巴西东北部人群中普遍存在的黑人和白人混合情况与观察到的基因频率非常吻合。有两个样本呈现出变异的电泳图谱。
