Abstract
Apparently identical twin boys are both XX/XY and have two populations, A1 and B, of cells in their peripheral blood. Chimerism in somatic tissue outside the blood cells can be demonstrated in only one of the twins. From analysis of chromosomes and many gene markers the mechanism of origin of the unusual twins remains unclear.
摘要
表面上看起来一模一样的双胞胎男孩都是XX/XY嵌合体，其外周血中有A1和B两个细胞群。血细胞以外的体细胞组织中的嵌合现象仅在其中一个双胞胎中得到证实。通过对染色体和许多基因标记的分析，这对非同寻常的双胞胎的起源机制仍不清楚。
