- The cloning involved differentiated cells from an adult mammal
- The DNA was removed from an unfertilized egg cell of 1 sheep
- An udder cell was removed from a different sheep
- The cells were fused with an electric shock
- The cells were developed in vitro (outside of a womb)
- The cells were implanted into a surrogate mother
