Researcher explores the current state of domestic animal cloning

Researchers are able to clone domestic animals using various techniques, including embryo splitting and nuclear transfer, but the expense and inherent inefficiencies of most cloning processes have limited procedures to research and certain agricultural activities. Carol L. Keefer of the Department of Animal and Avian Sciences of the University of Maryland has contributed a paper to the Proceedings of the National Academy of Sciences that provides a contextual overview of the innovations and contributions of cloning while seeking to answer an important question: If cloning is impractical and inefficient as a means of producing animals, and in the absence of societal acceptance for transgenic products, how is artificial cloning being used?
