Question
Chapter 38.3, Problem 1R
Summary Introduction
To review:
(a) The physiological and genetic effects of reduced rainfall on wheat yields in Pakistan.
(b) The physiological and genetic effects of rising sea levels on the rice fields in the Mekong Delta of Vietnam.
Introduction:
The growth and yield of important crops, like wheat and rice, are widely affected by the changing climatic conditions. Temperature extreme, reduced or increased rainfall, global warming, and rising sea levels have both physiological as well as genetic effects on the crop plants and therefore affect plant breeding practices.

Normally, wild violets have yellow petals with darkbrown markings and erect stems. Imagine you discover a plant with white petals, no markings, andprostrate stems. What experiment could you performto determine whether the non-wild-type phenotypesare due to several different mutant genes or to thepleiotropic effects of alleles at a single locus? Explainhow your experiment would settle the question.
A plant breeder wants to use selective breeding to produce corn with short stalks and a high mass of grain.He could use the following varieties of cor, A, Long stalks, high mass of grain, B, Short stalks, low mass of grain or c, Long Stalks, low mass of grain. What would the plant breeder need to do to make sure he always produced corn with a short stem and a high mass of grain? Describe three steps the breeder would use.

- Consider the following hypothetical gene a plant. Gene T produces a protein that impacts stem length. There are two alleles for gene T, T which produces long stems and t which results in short stems.

- A large, genetically heterogeneous group of tomato plants was usedas the original breeding stock by two different breeders, namedMary and Hector. Each breeder was given 50 seeds and began aselective breeding strategy, much like that described in Figure24.11. The seeds were planted, and the breeders selected the 10plants with the highest mean tomato weights as the breeding stockfor the next generation. This process was repeated over the courseof 12 growing seasons, and the following data were obtained: A. Explain these results.B. Another tomato breeder, named Martin, got some seeds fromMary’s and Hector’s tomato strains (after 12 generations),grew the plants, and then crossed them to each other. The mean weight of the tomatoes in these hybrids was about 1.7 pounds.For a period of 5 years, Martin subjected these hybrids to thesame selective breeding strategy that Mary and Hector had followed,and he obtained the following results: Explain Martin’s data.

Teosinte looks like a terrible plant to begin to domesticate for agricultural purposes. What hypothesis is put forth to explain farmers’ early interest in the plant? C. Often successful domestication of a plant or animal is due to the fact that this involved just a few gene changes. In what situation can changes in just a few genes dramatically change an organism's entire appearance? D. Who is Norman Borlaug?arrow_forwardA snapdragon with pink petals, black anthers, and longstems was allowed to self-fertilize. From the resultingseeds, 650 adult plants were obtained.

- Consider 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? And what would the phenotype be for the genotype?arrow_forward. The two loci P and Bz are normally 36 m.u. apart on thesame arm of a certain plant chromosome. A paracentricinversion spans about one-fourth of this region butdoes not include either of the loci. What approximaterecombinant frequency between P and Bz would youpredict in plants that area. heterozygous for the paracentric inversion?b. homozygous for the paracentric inversion?arrow_forwardA plant believed to be heterozygous for a pair of alleles B/b (where B encodes yellow and b encodes bronze) was selfed, and, in the progeny, there were 280 yellow and 120 bronze plants. Do these results support the hypothesis that the plant is B/b?arrow_forward
- The purple colour results from the formation of a purple pigment in the skin of the kernel. The gene locus for the colour trait is designated “R”. The wrinkled phenotype arises from a decrease in the amount starch produced within the kernel. The gene locus for the texture trait is designated “S”. Present the data as monohybrids (Xx, XX, xx) for all five corn cobs andfor the plant. Present the colour and texture phenotypes with their associated genotypes in separate tables. Your first table should include the corn ID, the number of purple kernels, the number of yellow kernels, and the phenotypic ratio between the two kernel colours. Present the texture results in the same format to a separate table. What is the dominant phenotype for kernel colour in your assigned cornplant? What is the dominant phenotype for kernel texture in your assigned cornplant?arrow_forwardA genetic cross was made between two types of pea plants. One type produces round and green seeds, while the other type produces wrinkled and yellow seeds. A plant breeder crossed these two types and then allowed the F1 generation to self-fertilize. The following data were obtained: F1 generation: all produce wrinkled and yellow seeds. F2 generation: 157 produce wrinkled and yellow seeds 57 produce wrinkled and green seeds 54 produce round and yellow seeds 20 produce round and green seeds a) Propose a hypothesis that you think is consistent with the observed data. b) Test the goodness of fit between the data and your hypothesis using a chi square test. c) Explain what your calculated chi square results mean.arrow_forwardA large, genetically heterogeneous group of tomato plants was usedas the original breeding stock by two different breeders, named Maryand Hector.
