It is a new highly important technique in modern biotechnology, genetics and medicine. Dolly, the sheep\u2019s birth in 1996, was the first mammal to be cloned from an adult somatic cell. This process brought global attention to the possibilities and dilemmas of cloning. While cloning has high potential in scientific research, agriculture, and regenerative medicine, it also raises profound ethical, social, and ecological questions, particularly when extended to humans and higher animals. In this article, we are going to cover cloning, its types, advantages as well as disadvantages.\u00a0<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Cloning\u00a0\u00a0<\/span><\/h2>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Cloning refers to the process of creating an exact genetic replica of another entity.
