On a prezygotic origin of normal/balanced translocation mosaics.
Based on a theoretical model for the production of some structural mosaicisms, the authors propose a mechanism for the origin of normal/balanced translocation mosaics. Single strand breaks and nonhomologous hemichromatid joining are implicated and, when applied to homologous chromosomes, could explain some instances of nondisjunction independent of centromere function.
