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?

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?
A consortium of dairy and beef farmers has hired you to study the evolutionary origins of domestic cattle. They particularly want to know whether the humped zebu cattle of Asia and the cattle of Africa are derived from different species of wild cattle than European breeds. Outline a complete research program to study this question. Describe the sequence of steps you would need to do, what kind of data you would collect, and the methods you could use to evaluate possible trees and branches.
Plant 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.

The table shows each of three possible fruit tree genotypes and the percentage of fruit produced at different temperature ranges. Which of the following statements best describes the evolutionary concept illustrated by this example? A. Homozygous genotypes increase fitness in a population. B. Hybrid plants are known to have a disadvantage over homozygous genotypes. C. Natural selection selects against the recessive gene and for the dominant gene. D. Certain phenotypic variations can significantly increase fitness of the organism in particular environments.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

(1arrow_forwardOne problem with this line of criticism is that it is difficult to distinguish good forms of manipulating nature from unacceptable ones. Some critics of GMOs argue that we ought to leave species as we find them, and that it is the cross-species transfers of genetic material involved in some GMOs that make them unacceptable. One problem with this objection is that similar transfers have occurred in nature—from basic plant genetics to the long-term patterns of evolution. Please explain what does it meanarrow_forward

These ducks can’t fly, but there’s really no need to fly since there are no predators. In fact, they have an advantage because they don’t have to eat as much to support those big wings like the other ducks. Over time, the flightless ducks reproduce better than the regular ducks, and eventually all the regular ducks die out. What characteristic of life is being demonstrated here?
