Abstract

Details of placentation and zygosity are reported from a survey of 627 consecutive twin births at three hospitals in Northern Nigeria. Zygosity was determined by study of sex, red cell antigens (ABO, MNSs and Rh) and placental enzymes (PGM1, PGM2, PGM3 and Pep A). The proportion of DZ twins amongst the various ethnic groups in this part of Nigeria is intermediate between that found amongst Yorubas in Western Nigeria and populations in the U.S.A. and England.

摘要

尼日利亚北部三家医院对627例连续双胎分娩进行调查，报告了胎盘形成和合子性的详细情况。通过对性别、红细胞抗原（ABO、MNSs和Rh）以及胎盘酶（PGM1、PGM2、PGM3和Pep A）的研究来确定合子性。在尼日利亚这一地区，不同种族中双卵双胎的比例介于尼日利亚西部约鲁巴人和美国及英国人群之间。
