Single-cell embryos contain a set of maternal and paternal chromosomes, and as the embryo grows, daughter cells receive a copy of each. In a new study, researchers have discovered errors during the earliest stages of embryonic development can lead to entire sets of maternal and paternal chromosomes segregating into different cells, resulting in chimeric embryos.
