Work in groups. Read the following proposals for experiments involving genetic engineering. Note the public’s concern about the danger of each experiment.

Decide which experiments should be conducted. Rank these choices from the one you think is the most important (number 1) to the one you think is the least important (number 4) for improving today’s world.

Try to reach a group consensus.

v Character trait selection

These experiments would attempt to transfer genes to embryos and develop the cloning process. By selecting and transferring special genes to animals, farmers could develop a system for human gene selection. Parents would be able to .choose the genetic traits of their children.

Public concern: Choosing character traits is not ethical. It is cruel to animals to use them for this experimentation

v Cure for diseases

These experiments would develop a cure for diseases by manipulating genes in humans. Scientists hope to clone virus genes in order to treat patients and eventually develop a cure for the disease.

Public concern: The treatment could affect normal cells in the body and hurt the patient. Side effects from these drugs might be passed on to future generations.

v Military development

These experiments would attempt to create biological weapons by means of gene splicing and recombining DNA. Some countries are already working on these experiments and could take a lead in military power with these new weapons.

Public concern: The development of these weapons could increase the possibilities of biological warfare.

v Fertility regulation

These experiments would attempt to clone hormones to regulate fertility in humans. Experiments would also develop techniques for artificial insemination and embryo transfer.

Public concern: The hormones could get out of control and a person might become “too fertile”, conceiving more children than desired. Fertilization experiments tamper with nature.

Prepare a presentation on the topic being discussed.
