For example,
chromosome 1 of C. neoformans
contained pieces of four different
chromosomes from C. amylolentus, providing evidence of
multiple translocations, some within the centromere.
The finding that normal fertilization can result in embryos
containing cells with different parental sets of
chromosomes is a new mechanism for chimerism, which was previously thought to occur only as the result of fertilization errors, for example, the fusion of
multiple sperm or eggs to form an embryo.
