The mares of the photo are mother and daughter, but also the twin sisters, since the newborn is the clone of the mother. It is the first horse born by cloning and the second equine. The first was born in May, the Idaho Gem command. Both achievements have been important because of the difficulty of cloning the epics.
But the colt Promete is also special for another reason, since it is the first animal that is the clone of his mother. In animals cloned so far, breeding has not been a clone of their mother, but of another specimen. The mother has been somehow rented. In this case, the genetic information of the newborn has been extracted from a maternal cell. Therefore, they are also mothers and twin daughters.
