Cyndi grows thousands of B. rapa plants from seed and carefully watches for any unusual plants that might be a new mutation. She has been watching a small seedling whose leaves continue to develop, but the stem is not elongating. The result is a cluster, or rosette, of leaves sitting just above the soil surface. After 15 days the plant is beginning to produce flowers but is still a rosette. Cyndi is encouraged and hypothesizes that rosetteis a recessive mutation. -Describe the first cross she should make and the predicted results. Because B. rapa is an annual plant, the one rosette individual dies. Cyndi would like to continue her study of this mutation, but all od the offspring from her original cross were normal. There are no more plants with the rosette mutation. -What can Cyndi do to continue her investigation of rosette? What would be the results of these "next steps"? -What results would you expect if Cyndi crosses her new generation of rosette plants with a known heterozygous…
the photos below show flowers from two Arabidopsisplants. The plant on the left is wild-type (unmutated); theother carries a mutation that causes its flowers to havesepals and petals instead of stamens and carpels. Themutation inactivated one of the plant's ABC floral identity genes. Refer to Figure 10.8 and decide which gene(A, B, or C) has been inactivated
You are a developmental geneticist studying flowering time variation in Arabidopsis. You perform a mutagenesis screen to identify mutants in the photoperiod pathway. Given what you know about photoperiodism in Arabidopsis, what phenotype are you looking for and under what photoperiodic conditions would you perform the experiment? delayed flowering in long days delayed flowering in short days same flowering in short days early flowering in short days same flowering in long days early flowering in long days
What is mutation? Explain the significance of mutation in plant breeding. Give an example of a disease resistant variety of cultivated plant induced by mutation.
A mutation that breaks which of the following genes would be most likely to produce theanthocyanless phenotype of the green-stem Wisconsin Fast Plants (meaning no purple stems):PAL, CHS, C3H, FLS, or DFR? Explain your reasoning.
You are a developmental geneticist studying flowering time variation in Arabidopsis. You perform a mutagenesis screen to identify mutants in the photoperiod pathway. You conduct the screen and find two different plants that show the same mutant phenotype. You then use a complementation test. What is the predicted outcome of this test if both phenotypes are caused by mutations in separate genes? recover the wild type phenotype overexpress the gene O recover the mutant phenotype
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.
You are a developmental geneticist and perform a mutagenesis screen in Arabidopsis looking for floral organ mutants. You identify a mutant phenotype that has the following organ arrangement, beginning in whorl 1: Sepal-Sepal-Carpel-Carpel Which class of floral identity genes has been mutated? A-B double mutant O A O SEPALLATA B с
For 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? O 100% 50% 0% 25%
When working on barley plants, two researchers independently identify a short-plant mutation and develop homozygous recessive lines of short plants. Careful measurements of the height of mutant short plants versus normal tall plants indicate that the two mutant lines have the same height. How would you determine if these two mutant lines carry mutation of the same gene or of different genes?
In a species of tree, seed color is determined by four independently assorting genes: A, B, C, and D. The recessive alleles of each of these genes (a, b, C, and d) produce abnormal enzymes that cannot catalyze a reaction in the biosynthetic pathway for seed pigment. This pathway is diagrammed as follows: A White precursor Yellow ----Orange----- Red --- Blue When both red and blue pigments are present, the seeds are purple. Trees with the genotypes Aa Bb Cc Dd and Aa Bb Cc dd were crossed. (a) What color are the seeds in these two parental genotypes? (b) What proportion of the offspring from the cross will have white seeds? (c) Determine the relative proportions of red, white, and blue offspring from the cross.
Three haploid fungal mutants that require compound W for growth were isolated. Each mutant contains a recessive allele in a single gene. Three compounds (A, B and C) in the biosynthetic pathway to W are known, but their order in the pathway is unknown. Each compound is tested for its ability to support the growth of each of the three mutants. Phenotypes of all of the three mutants are shown in the following table (“+" indicates growth, "-" indicates no growth). A C W Mutant 1 Mutant 2 Mutant 3 What would be the phenotype of a haploid mutant that contains both mutant alleles in mutant 2 and 3? Phenotype refers to growth or absence of growth on compounds A, B, C and WN. O Like mutant 1 O Like mutant 2 Like mutant 3 O Like wild type
