Chapter 30, Problem 12TYU
SCIENCE, TECHNOLOGY, AND SOCIETY
People have engaged in genetic manipulation for millennia, producing plant and animal varieties through selective breeding and hybridization processes that significantly modify the genomes of organisms. Why do you think modern genetic engineering, which often entails introducing or modifying only one or a few genes, has met with so much public opposition? Should some forms of genetic engineering be of greater concern than others? Explain.

Humans have engaged in genetic manipulation for millennia, producing plant and animal varieties through selective breeding and hybridization that significantly modify genomes of organisms. Why do you think modern genetic engineering, which often entails introducing or modifying only one or a few genes, has met with so much opposition? Should some forms of genetic engineering be of greater concern than others? Explain.
Genetic engineering:
If you have the science to back you up, and you can actually "produce" offspring with traits of your liking, would you do it? If you have to limit this, what should these limitations be?
Genetic engineering has been a debatable topic in science as many people are only aware of its risk than benefits. Which among the scenarios below are the benefits of using GMOs?
I. Genetic engineering in food can be used to alter genes in crops leading to new diseases in pants.
II. Genetic engineering in crops such as rice, corn and tomato can be used to obtain new strains with better nutritional qualities.
III. Genetic engineering in food can be used to create totally the same substances such as proteins and other food nutrients.
IV. Genetic engineering can be used to increase the immunity to diseases in plants leading to uncontrolled transfer of the resistance genes to the harmful pathogens.
V. Genetic engineering can restrict the diversity in organisms.
VI. Genetic engineering can be used to suppress negative traits in human like certain genetic diseases.

- Improving the nutritional value of food has long been one of the goals in agricultural genetics. Crossing different strains of plants and animals followed by generations of artificial selection have yielded some successes, including the development of high-protein maize. The use of gene transfer biotechnology has led to other advances, including the creation of nutritionally enhanced rice to combat vitamin A deficiency and blindness. Researchers are now turning their attention to the nutritional enhancement of animals that are used as food. Scientists are now turning their attention to using gene transfer technology to nutritionally enhance animal foods. Recently, biotechnology was used to produce a sheep with increased amounts of an omega-3 essential fatty acid that plays an important role in the development of the nervous system and, in adults, reduces the risk of coronary artery disease. Once a small number of transgenic animals have been produced, they can be bred by conventional methods to establish a source of nutritionally enhanced meat and milk. The use of biotechnology is presenting consumers with many new choices, which will become more common in the future. Increasingly, we will all have to educate ourselves about the pros and cons of such decisions. On the other hand, how would you explain your preference for meat from animals without higher levels of beneficial fatty acids?arrow_forwardImproving the nutritional value of food has long been one of the goals in agricultural genetics.

- You are discussing with some of your bio major friends who have not taken Genetics and your non-bio major friends about how characteristics such as blue eye, light skin pigmentation, and light hair color, derived from a mutation that occurred about 10,000 years ago in Europe. Your friends are not very happy that you used the word mutation to describe the origin of human characteristics associated with light pigmentation. At that moment you only recall that green eye, fair skin and red hair in Neanderthals was due to other alleles and you mention that to them as an example of genetic determinants in species of the genus Homo. They are not convinced of your choice of the word mutation. Then you remember part of one of the papers that you read for Minicourse 5 regarding the OCA2 allele. “OCA2, homologous to the mouse pink-eyed dilution gene, encodes the human protein P, an integral membrane protein involved in both the transport of tyrosine and that helps in the regulation of…arrow_forwardLiving things and molecular biology are used in the science-based industry sector of biotechnology to create medical products.

These genes can be selected for during natural selection (which drives evolution) and artificial selection (which drives domestication of dogs, crops, etc). During the domestication of modern tomato, describe the traits that were and were not selected. In your own words, describe in 2-3 sentences why domesticated tomatoes bought at a grocery store are lackluster compared to heirlooms or wild tomatoes. What are a few genetic and non-genetic traits that control tomato flavor and taste?arrow_forward
