Methods for generating embryos using pluripotent stem cells are provided. The subject methods include methods for generating chimeric embryos, wherein only a subset of the cells of each embryo are genetically identical to the pluripotent stem cells used in the generation process. The subject methods also include methods for generating embryos that are identical or are essentially genetic clones of the pluripotent stem cells (e.g., the resulting embryos are substantially identical, genetically, to the pluripotent stem cells used in the generation process).
