Scientists in the polo-obsessed nation [of Argentina] have produced the world’s first genetically edited horses, modifying DNA from a champion mare using a technique called Crispr to increase “explosive speed” in her offspring, said the paper.
The five foals, born in October and November, have mostly the same genes as award-winning Polo Pureza and should inherit her natural agility, according to the biotech firm behind the project. But by tweaking a specific gene associated with sprinting, they are engineered to one day outrun her.
When world-renowned polo player Adolfo Cambiaso’s “beloved stallion” Aiken Cura “limped off the field, and it became clear that the horse was in his final days”, he “decided to take a gamble” and asked a vet to save some of the horse’s skin cells. Cambiaso then had a Texas-based laboratory clone Aiken Cura, and later repeated the process with his champion mare, Dolfina Cuartetera.

Regulatory bodies are responding with caution. For example, the World Arabian Horse Organization has banned the registration of genetically modified horses, and the horse racing industry prohibits gene doping to maintain fair competition.
