The correct answer is option 2, Dolly. Dolly was the name given to the first cloned sheep. Cloning is the process of creating an organism that is genetically identical to another. In 1996, scientists successfully cloned a sheep using a technique called somatic cell nuclear transfer. The sheep was named Dolly in honor of Dolly Parton, since the cell used to create her came from a mammary gland. Dolly`s birth was a significant milestone in scientific research as it demonstrated the possibility of cloning mammals from adult cells. It opened up new possibilities and raised ethical concerns regarding the cloning of other species, including humans.
