Goat and sheep chimera "Geep" (date unknown)
Sheep/goat chimera. Chimera or chimaera, a creature that contains a mixture of genetically- different tissues, in this case those of a sheep and a goat. A chimera is created by mixing togeth- er the cells from separate embryos, and then impl- anting them into a surrogate mother. The composite nature of this chimera can be seen as areas of thin white goat fur, and thick grey sheep wool. A chimera has a composite nature because the embryo cells were only physically mixed together; no genetic material was transferred between them. Its sex cells also developed from either one embryo or the other, meaning that its offspring will be 'pure breeds', not another chimera.
