Genetically modified foods

  1. 1. Genetically modified foods<br />By Jack Keary Per 9<br />
  2. 2. Basic Principles of Genetics<br /><ul><li>When dominant alleles are present they will always exist in the organism. Dominant alleles take precedence over recessive alleles. When recessive alleles are present, they are only shown when a dominant allele is not present in the organism. If a dominant allele is present, the recessive allele will be covered up. These alleles in an organism help develop its traits.
  3. 3. Codominant alleles are not recessive or dominant. These alleles will not be covered up in the offspring and will be shown in the organism.
  4. 4. The alleles of two parents will be dominant or recessive. When they are combined, dominant traits mask up the recessive traits. Recessive alleles will be seen only if there is no dominant trait present. Codominant alleles will always be present in the organism if they are in the parents.</li></li></ul><li>Human Genome Project<br />The Human Genome Project began in 1990 and was finished in 2003. The goals earlier in the project were to classify the 20,000-25,000 genes which are contained in humans’ DNA, analyze the arrangement of 3 billion chemical base pairs which compose DNA, accumulate this information in databases, upgrade the tools for data analysis, moverelatedtechnologies to the private sector, and to approach the ethical, legal, and social issues which would potentially be seen as issues during the development of the project.<br />Some social, ethical, and legal implications with the human genome project were whether genetically modified foods and other genetically enhanced products were safe to be consumed in society or not and whether they were or were not safe for our environment. Another potential issue was how new genetically related technologies would affect growing nations’ reliance on western society and life. Lastly, another issue is whether genetically enhanced or modified products would affect the personalities and behaviors of people.<br />
  5. 5. Human Genome Project 2<br />On May 21st, President George Bush signed a law the Genetic Information Act (GINA) Because of this legislation, Americans will be free to undergo genetic testing for diseases such as cancer, heart disease, diabetes. Genetic testing also will help doctors catch problems early, perhaps leading to preventive treatment and lower costs. <br />
  6. 6. Argument 1<br />I think Genetically modified foods are bad for society because they could possibly present certain dangers to people’s heath. Golden Rice is rice that has been genetically engineered to contain beta-carotene and other carotenoids in the endosperm. When the rice is consumed, some carotenoids are converted in the body into vitamin A.I prefer white rice to golden rice because I would rather not take any chances when it comes to my health. Prior to knowing this I would have had golden rice, but now I know it is Genetically modified so I would prefer to play it safe and spare myself to the potential risk it brings to my health. Originally golden rice did not provide the needed amount of vitamin A and if mistakes like this were made, then many others may have been made as well.<br />
  7. 7. Argument 2<br /><ul><li>Society often argues with the safety of consuming genetically enhanced foods and continue to question, as the industry continues to grow, if consumers will realize whether or not what they are consuming is genetically enhanced. Certain laws have been passed, requiring strict regulation of genetically modified foods, but many people and myself still believe that genetically modified foods are negative and will eventually pose as a large problem regarding food safety and labeling. </li></li></ul><li>Argument 3<br />Another problem that will be created by the continual production and popularity of genetically modified foods is that it would put smaller and less economically stable food producers or organic food producers out of business simply because they are unable to produce genetically modified foods. In this case small food producers who can’t afford to keep up with society’s changes in the food industry would be cut loose by society and would eventually wither away because they are unable to bring in enough money. Genetically modified foods could further monopolize the food industry and I think if we allow this to go on it would prove to be malignant.<br />
  8. 8. Argument 4<br />My last argument is that, despite the increasing amount of information about the potential health risks, there is still a lack of research about this considering that these products would be consumed by people and may directly affect their health. Although many people think that genetically modified foods can negatively affect the health of organisms, not much research has been done to confirm or disprove this theory. With a lack of existing evidence to help either side I do not think these foods should be eaten. If more evidence can be found, then further conclusions must be made about whether or not humans should consume these foods, but until that time these foods should not be eaten or produced.<br />
