Answer
- Dolly sheep
Explanation:
Dolly was the first mammal to be cloned from an adult somatic cell, using the process of nuclear transfer.
Dolly was cloned from a cell taken from the mammary gland of a six-year-old Finn Dorset sheep and an egg cell taken from a Scottish Blackface sheep.
Electrical pulses were used to fuse the mammary cell with an unfertilized egg cell, the nucleus of which had been removed.
This fusion process resulted in the transfer of the mammary cell nucleus into the egg cell, which then began to divide to form a complete embryo
