Genetics
This is an excerpt from the paper...
Genetics today is on the cutting edge of biological science, and scientists working in this area are involved in a wide variety of pursuits that will have profound implications for our future on this planet, with projects including the creation of new biologic entities, curing diseases, manufacturing synthetic versions of biologic substances, identifying different genetic codes and what they do, and perhaps finding a way to control that genetic information to produce animals with certain characteristics or without certain characteristics, including greater strength, resistance to disease, and a higher yield in meat, eggs, dairy products, or whatever they provide. Geneticists have already accomplished many of these things with grains, plants, and even certain farm animals. Such advances in medicine and biology offer great possibilities for future medical procedures and for entirely new procedures such as genetic splicing to create new forms of life for good or ill. These new possibilities bring with them great responsibility and require that experimentation and development in biology be conducted following ethical precepts. Some people are concerned about any and all forms of genetic engineering, as if the danger was just too great. The most recent flap has concerned the possibility of the cloning of human beings. One can support a variety of approaches to genetic engineering involving gene splicing and recombinant DNA research and still oppose human cloning, and a clea

ip. Clone refers to asexual reproduction, or vegetative reproduction. The cloning of plants is an established practice because of the ease with which plants are propagated or cloned from a twig or a slip. The essential fact of sex in both plants and animals, that hereditary material from two individuals is joined to form a new creature. The sex cells provide diversity so that each offspring produced is unique in its combination of traits. Cloning does not involve sexual reproduction, and so the cloned plant is not the result of a union of different material. The plant produced by cloning is a manifestation of the capacity for new growth of the old plant body, so the new plant is usually genetically identical to the old plant. Cloning is used in agriculture to produce high-quality, uniform products (Carney 641).
Cloning of animals is less common, but there is a procedure well established for permitting asexual reproduction in amphibians such as toads, frogs, and salamanders. This procedure is known as nuclear transplantation and is widely referred to as cloning. Frogs were the first multicellular animals cloned because they have an abundant supply of eggs and sperm that experimenters can use. The fertilization and embry
