Chimera (mythology) (that does not occur with depictions of male lions). Sighting the Chimera was an omen of storms, shipwrecks, and natural disasters (particularly volcanoes). While there are different genealogies, in one version the Chimera mated with her brother Orthrus and was the mother of the Sphinx and the Nemean lion (others have Orthrus and their mother, Echidna, mating; most attribute all to Typhon and Echidna). The Chimera finally was defeated by Bellerophon with the help of Pegasus, at the command of King Iobates of Lycia, after terrorizing Lycia and nearby lands. Since Pegasus could fly, Bellerophon shot the Chimera from the
Chimera (genetics) give rise to the embryo proper. Embryos that are to be used in chimeras can further be genetically altered in order to specifically contribute to only one part of chimera. An example is the chimera built off of ES cells and tetraploid embryos, which are artificially made by electrofusion of two two-cell diploid embryos. The tetraploid embryo will exclusively give rise to the trophectoderm and primitive endoderm in the chimera. There are a variety of combinations that can give rise to a successful chimera mouse and — according to the goal of the experiment — an appropriate cell and embryo
