From: Characteristics and mechanisms of mosaicism in prenatal diagnosis cases by application of SNP array
SNP array of six cases with mosaic double trisomies and one case with mosaic near-diploid. The mechanisms of mosaic double trisomies and near-diploid are intricate; with the possibility of either congruous or incongruous origins for the affected chromosomes. The occurrence of errors in A, B, D, and F is characterized by varying mosaic frequencies across different chromosomes. The origin of C and E were from mitotic non-disjunction errors. G was from a meiosis II non-disjunction error with simultaneous occurrence at the same mosaic frequencies
