A major milestone in chimera experimentation occurred in 1984, when a chimeric geep was produced by combining embryos from a goat and a sheep, and survived to adulthood.

In implanting a goat embryo for gestation in a sheep, the sheep's immune system would reject the developing goat embryo, whereas a "geep" embryo (sharing markers of immunity with both sheep and goats) was able to survive implantation in either of its parent species.
