These skin samples which are rich in DNA, have led scientists to extract their nuclei. The nuclei are inserted into the egg cells of domestic goats. After stimulating growth of the egg cells by applying a jolt of electricity, the ovum is implanted into a surrogate, which in this case a close relative of the Bucardo.
