The Retnup Stem Cell Foundation has verified that one of Black Caviar's eggs has been successfully cloned and transferred to a surrogate mare who will carry the egg to term. The foal will essentially be Black Caviar's twin, and will share the champion mare's DNA.
Whether the foal will ever be able to race is undecided; Australian racing authorities state that cloning a Thoroughbred racehorse breaks racing rules. Other famous horses have been successfully cloned, including show jumper Gem Twist, barrel racer Scamper, and performance horse Smart Little Lena.
Black Caviar raced from 2008 to 2013 and was undefeated in her 25 races. She retired on April 17, 2013 and is currently in foal to Exceed and Excel. Her career earnings total $7,953,936, a sign of the possible value of another racehorse of her caliber.
