There are basically three forms of genetic engineering that are common today, selective breeding, hybridization, and recombinant DNA, or gene splicing. Selective breeding has been popular since after the Second World War, and is still used today. This method is most co

To some genetic engineering might seem as a new application of technology that can have a positive impact on society, however there are many underlying issues that are making some question how ethical and safe it really is. Critics of recombinant DNA fear that the disease producing organisms used in some experiments might develop extremely infectious forms that could lead to a worldwide epidemic. Animal rights groups have also argued that genetically altering the DNA of animals might pose problems for reproduction. Genetically altered animals might not interact with normal animals and most importantly have problems concerning reproduction. Also there is a fear that by introducing genetically altered animals to normal animals might change the behavioral patterns of regular animals. Environmentalists also fear that plants that have been genetically tampered with might have an adverse affect on other plant life in surrounding areas. They could interbreed with weeds and produ!

mmonly for increased food production; only the plants and animals that have desirable characteristics are chosen for reproduction. A popular example is the selective breeding of corn for increased kernel size and for nutritional content for over 7,000 years. Hybridization, or crossbreeding, involves combining different forms of species to combine the positive traits of both. In
