Textbook Question
Chapter 1, Problem 18TYK
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?

Certain genetically modified tomatoes were designed to suppress (reduce the effectiveness) the enzyme polygalactias which delays ripening.
How does this gene modification affect the consumer and the diet of individuals in developing countries?
options:
Delaying the ripening process means that the tomatoes have a longer shelf life. The tomatoes survive delivery to the consumer and provide nutritional value to more people.
Delaying the ripening process means that the tomatoes can stay on the vine longer to receive nutrients. Once picked, these tomatoes will ripen rapidly to provide a full taste to the consumer.
Delaying the ripening process means that the tomatoes are more likely to freeze on the vine before becoming ripe. This freezing process locks in the minerals and beneficial nutrients so that the tomato can be transported without losing its nutritional benefit.
Delaying the ripening process means that the tomatoes are more likely to have a shorter shelf…
In most parts of the world, commercial potato crops are produced asexually by planting tubers. However, in some regions of the world, such as Southeast Asia and the Andes, some potatoes are grown from true seeds. Discuss the advantages and disadvantages of growing potatoes from true seed.
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).

- When tomatoes are fully ripe, they develop bright red skins. William recently built a garden and decided to investigate tomato reproduction. He found that green tomatoes (not fully ripe) have an 18% chance of germinating while red tomatoes (fully ripe) have a 78% chance of germinating. Based on the data provided from the investigation, explain what characteristic(s) contributes to the probability of the tomatoes reproductive success and what factors (genetic or environmental) might impact the growth and development of the tomatoes. Answer should be based on : Claim: includes the idea that characteristic animal behaviors or specialized plant structures affect the probability of successful reproduction. Evidence: supports claim including: -behaviors and/or structures that increase the probability of reproduction -cause and effect relationship between the behavior/structure and the successful reproduction of organisms that have them -plant reproduction and the animal behaviors…arrow_forwardYou 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…arrow_forwardGenes 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?arrow_forward
- Create three Venn Diagrams. For the first diagram, identify two or three similarities and differences between plant and animal reproduction; for the second, two or three similarities and differences between plant and animal development; and for the third, two or three similarities and differences between plant and animal nutrition. Make your diagram on a separate sheet of paper or at the back of this answer sheetarrow_forwardIn early spring, Dr. Tom Wilson notices that there is an equal distribution of long and short stemmed buttercups in the vacant lot across the street from his house as well as in his own backyard. In late summer he notices that there are mostly long stemmed buttercups in the lot, but mostly short stemmed buttercups in his yard. These observations are examples of what biological principle? Develop a hypothesis to explain Dr. Wilson's observations.arrow_forwardConsider the following hypothetical gene a plant g&T produces a protein that impacts the stem length. There are two alleles for GT which produces long stem and tea little tea which results in short stint. Which of the following genome types above would have a different pheno type?

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_forwardAn advantage of using genetically modified plants is that they may possess superior characteristics to the original plant. are genetically identical to the parent plant. grow much more quickly. cannot undergo asexual reproduction. are always virus-freearrow_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_forwardthis is an example of biotechnology: In order to increase the yield of oil from canola, research focused on ways to reduce competition from competitor weed plants. Weeds can be controlled by spraying with a herbicide that interferes with biological processes, like amino acid anabolic reactions, in the plant cells. A mutant of canola that is resistant to herbicides is sometimes grown in fields that are sprayed with the herbicide. The majority of canola in Canada, though, is genetically modified to be resistant to herbicides. also use the link: https://youtu.be/VS3kcwgIwm0 Question: Evaluating Biotechnologies in Food Systems As we practice being able to describe choices in Biology you will use this consolidation task to organize details about the advantages and disadvantages of biotechnologies.
