Proposed mechanisms to explain chimera. (A): Fusion of two distinct embryos. (B-1, B-2): Double mitotic nondisjunction of a 47,XXY zygote or sequential nondisjunction events in a 47,XXY single lineage. (C): Fertilization of one parthenogenetic ovum by a spermatozoon, and the diploidization of the other. (D): Parthenogenetic division of two identical ova, which were fertilized by two spermatozoa respectively.
