Textbook Question
Chapter 1, Problem 13PS
The fruits of wild species of tomato are tiny compared with the giant beefsteak tomatoes available today. This difference in fruit size is almost entirely due to the larger number of cells in the domesticated fruits. Plant biologists have recently discovered genes that are responsible for controlling cell division in tomatoes. Why would such a discovery be important to producers of other kinds of fruits and vegetables? To the study of human development and disease? To our basic understanding of biology?

You have been put in charge of developing a breed of domesticated dog that lives to be 40 years old on average. You will need to brainstorm for several minutes on how you could extend the life of dogs. You should refer to the example of the fruit flies from lecture.As part of this project, the breeders will need to put together an informational brochure to hand out to veterinarians and prospective owners of the dogs, which discusses: first, how dogs' age will be extended, then, some of the potential consequences of having a pet that lives for such a long time. The brochure will need to inform prospective owners that these dogs may live 40 or more years. It should point out that someone who is 30+ years old may have to plan on care for the pet if it were to outlive him or her. Also, there will be more lifetime costs associated with these dogs simply because they live so long. These dogs may be prone to diseases that are not seen in dogs with shorter life spans. Finally, there may be…
Trace the genetic steps in the development of a peanut plant that isresistant to insect larvae (table given). (Hint: You need to useAgrobacterium.)
Genes control thousands of different traits in plants. 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?

- Genetic engineering of plants provides an opportunity to alter their properties or performance in order to improve upon their utility. Such technology may be used to modify the expression of genes already present in the plants, or to introduce new genes of other species with which the plant cannot be bred conventionally. In fact, humans have engaged in genetic manipulation for millennia, producing plant and animal varieties through selective breeding and hybridization that significantly modify genomes of organisms. How has this technology created novel genetic information by specific alteration of cloned genes? (provide an example). Why do you think modern genetic engineering, has met with so much opposition? Should some forms of genetic engineering be of greater concern than others? Explain. In your response provide a specific example from literature to describe the implications of this technology (good or bad).arrow_forwardPlant seeds contain storage proteins that are encoded by the plant’s genes. When a seed germinates, these proteins are rapidly hydrolyzed (i.e., the covalent bonds between amino acids within the polypeptides are broken), which releases amino acids for the developing seedling. Would you expect the genes that encode plant storage proteins to evolve more slowly or more rapidly than genes that encode enzymes? Explain your answer.arrow_forwardHumans have been selectively breeding corn for generations. During the process of domestication, the wild form of corn was eventually changed into a form that has more favorable traits. Early farmers most likely used corn seed that had – thin stalks to withstand stronger wind. a darker color so that they would blend with the field and be protected from predators. larger leaves that could be used for compost. the ability to grow in a large number of climates, soil types, and produced the largest amount of kernelsarrow_forward
- The genetic modification of plants for food is a hot-button issue around the world. Genes transplanted to corn, potato, soybean, and other food strains can confer desired traits, such as resistance to pests, which lessens the need for toxic pesticides. Though genetically modified foods are thought to be safe to eat, their impact on the environment may not be fully known. Do you worry about the long-term effects of genetically modified foods on your health, or the health of the environment? Do the positive impacts outweigh the negatives?arrow_forwardAround 8,000 years ago wild potato's were being harvested by humans in South America. They were from warm regions of Peru, and had tiny tubers. In the 16th century, European's introduced these tiny potato's to Europe. Over time, larger potato varieties appeared. Today, many varieties exist, such as this Idaho potato. Recently, a gene for tuber size was discovered, larger size is related to variation in the gene pool (potato's growing in cooler areas show higher frequencies). Questions: What kind of selection was going on here, why would small tuber size be more common in the tropics, how does founder effect come into play here for our current larger potato varieties? Lastly, what is the point of a tuber in a plant? Original varieties of potato Idaho potatoarrow_forwardAn agriculture lab is trying to improve a type of tomato so that it produces large fruits even under very hot, dry conditions.

Susceptibility of crops to insect pests. 3 Accumulation of toxic ions in agricultural soils. 4. Both 1 and 2 are correct. 5. Women menstruation cycle.arrow_forwardThe farmer finds that many of the tallest corn plants are also very susceptible to a particular disease. How would the farmer design an experiment to find out if the genes for height are linked to the genes for resistance to the disease?arrow_forwardImproving 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. How would you explain your decision to eat nutritionally enhanced meat from animals modified by biotechnology?arrow_forward
