chimera (biology)
Chimera (biology)
In biology, an organism composed of tissues that are genetically different. Chimeras can develop naturally if a mutation occurs in a cell of a developing embryo, but are more commonly produced artificially by implanting cells from one organism into the embryo of another.
In the context of cloning research, chimeras between different animal species have been produced. In 2003, Chinese researchers stirred controversy with the production of an early stage embryo combining rabbit and human parts.
