A sheep–goat chimera (sometimes called a geep in popular media [13]) is a chimera produced by combining the embryos of a goat and a sheep; the resulting animal has cells of both sheep and goat origin. A sheep–goat chimera should not be confused with a sheep–goat hybrid, which can result when a goat mates with a sheep.

There have been incidents of polycerate goats (having as many as eight horns), [9] although this is a genetic rarity thought to be inherited. The horns are most typically removed in commercial dairy goat herds, to reduce the injuries to humans and other goats. 4 horns are the norm for the Austrian goat breed Vierhornziege (four-horned goat). [10]
The Icelandic [a] is the Icelandic breed of domestic sheep.It belongs to the Northern European Short-tailed group of sheep, and is larger than most breeds in that group.. It is generally short-legged and stocky, slender and light-boned, and usually horned, although polled and polycerate animals can occur; there is a polled strain, the Kleifa.
Goat fetuses have likewise been successfully grown in sheep wombs by enveloping the goat inner cell mass in sheep trophoblast. [16] Such envelopment can be created by first isolating the inner cell mass of blastocysts of the species to be reproduced by immunosurgery , wherein the blastocyst is exposed to antibodies toward that species.
The term refers to both breeds and strains that are naturally polled through selective breeding and also to naturally horned animals that have been disbudded. [1] Natural polling occurs in cattle , yaks , water buffalo , and goats , and in these animals it affects both sexes equally; in sheep , by contrast, both sexes may be horned, both polled ...
