Abstract
Extraembryonic membranes and fetal tissues were obtained from 55 specimens of 5-11 wk conceptual age. The glucose-6-phosphate dehydrogenase (G6PD) electrophoretic phenotype was determined and correlated with that of maternal blood. Fifteen specimens were heterozygous for G6PD A, and for 9 of these the maternal allele could be determined. In none of these specimens did the isozyme pattern of the membraneous chorion or chorionic villi differ significantly from that of fetal tissue. No evidence of non-random inactivation in extraembryonic membranes of human fetal specimens at this stage of development was seen.This publication has 8 references indexed in Scilit:
