Concept explainers
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?

- A) Describe the data you collect from the Purple 1 x Purple 2 cross. Predict the genotype of each of the parent plants. Explain your predictions using data from the experiment. Â B) Consider the offspring, the next generation (F1), from the Purple 1 x Purple 2 cross. What is the probability of a green stem plant? How do you know this? Â C) What is the probability in the F2 generation of a green stem offspring? Use a Punnett square(s) and quantitative data to explain your thinking. Upload your Punnett square(s).arrow_forwardWhat is mutation? Explain the significance of mutation in plant breeding. Give an example of a disease resistant variety of cultivated plant induced by mutation.arrow_forwardHybridization of a homozygous dominant and homozygous recessive plant was conducted.

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.arrow_forwardA 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.arrow_forward
- 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. If gene T displays incomplete dominance, which of the following genotypes above would have a different phenotype? and What would the phenotype be for this genotype?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_forwardIn 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.arrow_forward

What is the probability that the F2 will have the phenotype big oval shaped yellow leaves, white flowers, and pink fruits? Hybridization of a homozygous dominant and homozygous recessive plant was conducted. What is the probability that the F2 will have the phenotype green, small and spade shaped leaves with pink and rounded fruits? Hybridization of a homozygous dominant and homozygous recessive plant was conducted. What is the probability that the F2 will show only all the dominant phenotypes? Hybridization of a homozygous dominant and homozygous recessive plant was conducted. How many of 10,000,000 F2 progeny will have a fully heterozygous genotype?
