Chapter 12, Problem 42P
Summary Introduction
To determine:
The ways by which a diploid cell line can be obtained from a haploid tobacco cell.
Introduction:
The transgene is a type of gene that has been transferred from one organism to another by a technique called genetic engineering. The cells in which a foreign gene has been inserted are called transgenic cells.

- During the course of a research project you generate a gene knockout line in Arabidopsis thaliana to study the function of a gene you believe plays a crucial role in cellular metabolism. You note that the initial transformants are a bit smaller than normal. In subsequent crosses you are unable to isolate homozygotes for the knockout allele. Heterozygotes in subsequent generation are still a bit smaller than the homozygous wild type plants. Explain what is happening.arrow_forwardWhat creates polyploid plants in the wild?

- You are studying a plant with tissue comprising both green and white sectors. You wish to decide whether this phenomenon is due (1) to a chloroplast mutation of the type considered in this chapter or (2) to a dominant nuclear mutation that inhibits chlorophyll production and is present only in certain tissue layers of the plant as a mosaic. Outline the experimental approach that you would use to resolve this problem.arrow_forwardYou have already localized the genes to the same chromosome by deletion mapping, and now decide that the best way to accomplish the mapping is to conduct two simultaneous three-point testcross experiments. The genes you are investigating are as follows: N = round leaves, n = notched leaves; H = smooth stems, h = hairy stems; R = purple flowers, r = red flowers; B = grey seeds, b = black seeds; and Y = green pods, y = yellow pods. Earlier experiments you have done already established that gene B is in the middle of this gene cluster, so you design both three-point test crosses to include that gene. Cross #1 is designed as RrHhBb x rrhhbb while cross #2 is NnBbYy x nnbbyy. The results of both crosses are given in the table below. Based on the information given, determine the arrangement of these five genes including the position of each allele in the heterozygous fly and the distances between each pair of genes. (Hint: treat each experiment separately, knowing that gene B is in the…arrow_forwardChoose which of the following is true: a) Haploid cells have one allele per gene b) Haploid cells have two alleles per genearrow_forward
- After genetic selection, some originally diploid species can become triploid, like for example some banana trees, grapevines and molluscs. These organisms are mostly sterile because they produce nearly no gametes. a) Make a drawing showing the chomosomes of a triploid cell where n = 2. b) Make a diagram showing how a triploid individual can be produced.arrow_forwardFor a haploid fungus, the starting point in the biosynthesis of the amino acid arginine is Compound X, which is always present in and absorbed from the environment. The arginine biosynthetic pathway is: Enzyme A Enzyme B Enzyme Ç Compound X It is know that genes encoding enzymes A and C are on two different chromosomes. Compound Y Compound Z- Arginine A mutant strain of genotype a (lacking only enzyme A) is crossed to a mutant strain of genotype c (lacking only enzyme C) to generate a diploid strain. Sporulation (i.e. meiosis) is subsequently induced in the resulting diploid strain. What proportion of the spores (haploids formed by sporulation) is expected to grow on medium without arginine but supplemented with Compound Y?

- What practical applications could be made with male sterile lines of maize?arrow_forwardIn a genetic laboratory, a plant species was subjected to radiation to produce chromosome mutations. The mutated plant was then inbred for many generations until it was true breeding for all of these mutations. It was then crossed to the original non-mutated plant, and the meiotic process of the F1 hybrids was examined. In the examination, a cell with a dicentric chromosome and an acentric fragment was noticed in anaphase I of the hybrid. (i) What kind of chromosomal mutation occurred in the irradiated plant? In your answer, indicate the position of the centromere. (ii) Diagram the alignment of the chromosomes during meiosis. Assume that the gene sequence in the original unirradiated plant is AB//CDEFGHIJK and the inverted region involved genes DEFGHI (double strokes indicate the position of the centromere). (ii) Diagram the results of a single crossover between homologous gene E and F in the inversion.arrow_forwardAn individual has a deletion of part of the short arm of chromosome 5. This individual also has a normal copy of chromosome 5. Would you expect this individual to have Cri-du-chat syndrome? Why or why not? Question 7 options: A) Yes, because they will inactivate their normal chromosome 5 B) Yes, because they only contain one copy of some of their genes C) No, because this is a terminal deficiency D) No, because they still have at least one copy of all the genes on chromosome 5arrow_forward
