Researchers recently took equine cloning science a step further when the world’s first filly produced by a clone and out of a clone was born. Or, more simply put, the world’s first clone-to-clone foal.

To produce the foal, tissue and DNA samples from champion bucking gelding Go Wild were collected, frozen, and used after his death to produce three clones: Go Left, Go Right, and Go Straight. Semen from Go Straight was collected and used to artificially inseminate a filly clone of the infertile champion bucking mare Spring Fling.

Once the Spring Fling clone, Chloe, was confirmed pregnant, the embryo (developing fetus) was flushed from Chloe’s uterus and transferred to a surrogate mare that ultimately foaled the filly.

Gregg Veneklasen, DVM, owner of Timber Creek Veterinary Hospital in Canyon, Texas, played a central role in producing the clone-to-clone filly, with his colleagues’ assistance
