A dog has just given birth to the world's first identical twin puppies
A dog has just given birth to the world's first identical twin puppiesAn Irish wolfhound has just given birth to the first identical twin puppies on record, delivered by veterinarian Kurt de Cramer at South Africa's Rant en Dal Animal Hospital.The pups are a rare example of monozygotic, or 'identical', twinning in mammals - something that's been reported in horses and pigs before, but appear to be incredibly uncommon in most species except for humans and armadillos.Twins can be either monozygotic (identical), meaning they develop from the same zygote (or egg cell), which is fertilised by the same sperm cell; or they can be dizygotic (fraternal), meaning they develop from two different egg cells, each fertilised by separate sperm cells.
