Question
Chapter 22.3, Problem 1COMQ
Summary Introduction
Introduction:
Reproductive cloning of an organism refers to the production of genetically identical individuals. It involves the extraction of mammalian embryos at an early stage of development, separation of embryonic cells and implantation of cells into the uterus in order to produce two or more identical individuals. Dolly was the first mammal which was cloned through the reproductive cloning technique.
