China claims a groundbreaking success in cloning the first Tibetan goats using the somatic cell cloning technique, the same method employed for Dolly the sheep in 1997.
The cloned goats, born through transferring the nucleus of an adult cell into a new egg cell, were announced by China Central Television. The news revealed that the first-born goat, weighing 3.36 Kg, is healthy. The cloning process involves implanting the modified egg into a surrogate mother, resulting in a baby with 100% of the donor’s DNA and zero per cent from the surrogate. The cloning process involves removing DNA from a donor cell, replacing the DNA of an egg cell, and implanting it into a surrogate, resulting in a genetically identical offspring. The successful pregnancy rate among 43 surrogate goats reached 58.1%, with 37.2% still pregnant at 120 days.
