sheep-goat chimera

Their sheep-goat chimera was published on the cover of Nature in February 1984, to enormous publicity.

A sheep-goat chimera should not be confused with a sheep-goat hybrid, which can result when a goat mates with a sheep.

The first sheep-goat chimeras were created by researchers at the Institute of Animal Physiology in Cambridge, England by combining sheep embryos with goat embryos.

A sheep-goat chimera (sometimes called a geep in popular media) 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 may be fertile, but it passes on either sheep or goat genes, depending on whether its reproductive organs were formed from the goat embryo or from the sheep embryo (i.e., whichever germ-line formed the ovaries or testes).

Too bad the old geep would never know how wrong he'd been.

But an adult geep gave birth to a sheep last summer.

"Feel a little better about the old geep's security?"

The most popular way of identifying a geep is to simply look at the animal's tail.

Still, Roland figured the geep wouldn't shoot him just yet.

Sure, the old geep should have taken off like he'd been told to do, probably he could have gotten away clean.

Does it take biology to make a geep?

A geep is produced by combining the embryos of a sheep and a goat.

They are not to be confused with geep, which are chimerae.

The creation of the "geep" revealed several complexities to chimera development.

The Geep name changed to Sandero in 1991 to avoid any copyright issues.

How good was this old geep?"

A. The tissues of a geep, for example, are partly sheep cells and partly goat cells.

The old geep had suckered them with his defenses, though at the end Sleel had seen through the holoproj.

Funny old geep.

Hybrids should not be confused with genetic chimeras such as that between sheep and goat known as the geep.

Squinting, he saw it was the geep again--the old Helvetian--come around to check up on him for whatever reason.

A geep's tail extends horizontally from the base of the spine combining the characteristics of a sheep's and goat's tail.

"Geep," as friends and co-workers called him, "would sometimes come in with his tie in disarray, or a shirt that just didn't match," Ms. Doria said.

Due to the mainstream focus of railroads on powerful six-axle units, the GP60 will most likely be the last new EMD "Geep".

In fact, a conversation early last week between offensive coordinator Greg Roman and quarterbacks coach Geep Chryst lay the foundation for Davis' dramatic catch.

George Patrick "Geep" Chryst is the quarterbacks coach of the San Francisco 49ers in the National Football League.

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.

He is the brother of former Mid-American Conference commissioner Rick Chryst and current San Francisco 49ers quarterbacks coach Geep Chryst.

Researchers at the University of California at Davis have fused a goat embryo with a sheep embryo and produced a living biological chimera they call a "geep," a less than hardy animal that cannot reproduce.
