. An allotetraploid species has a genome composed oftwo ancestral genomes, A and B, each of which havea basic chromosome number (x) of seven. In thisspecies, the two copies of each chromosome of eachancestral genome pair only with each other duringmeiosis. Resistance to a pathogen that attacks the foliage of the plant is controlled by a dominant allele atthe F locus. The recessive alleles Faand Fbconfersensitivity to the pathogen, but the dominant resistancealleles present in the two genomes have slightly different effects. Plants with at least one FAallele areresistant to races 1 and 2 of the pathogen regardlessof the genotype in the B genome, and plants with atleast one FBallele are resistant to races 1 and 3 of thepathogen regardless of the genotype in the A genome.What proportion of the self-progeny of an FA Fa FB Fbplant will be resistant to all three races of the pathogen?
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
Would you simply answer the question for me, i saw many answers for it
but still not sure.
The flower color of genetically identical hemp plants (clones) is purple
when the flowers develop under cold environment (30 °C). Describe in detail
a molecular mechanism that could explain how these two groups of
genetically identical plants differ in their gene expressions to produce
different flower colors?

- . Genomes A, B, and C all have basic chromosomenumbers (x) of nine. These genomes were derivedoriginally from plant species that had diverged from each other sufficiently far back in the evolutionarypast that the chromosomes from one genome can nolonger pair with the chromosomes from any other genome. For plants with the following kinds of euploidchromosome complements, (i) state the number ofchromosomes in the organism; (ii) provide terms thatdescribe the individual’s genetic makeup as accurately as possible; (iii) state whether or not it is likelythat this plant will be fertile, and if so, give the number of chromosomes (n) in the gametes.a.

- You join a project where the team is working on mapping three genes of a plant-like organism. The group is interested in three traits: flower color (red or purple; encoded by gene Color [C]), leaf texture (smooth or hairy; encoded by gene Texture [T]), and petal veins (present or absent; encoded by gene Vein [V]). One of the extraterrestrial geneticists (Dr. Jerry) hypothesizes that the genes for these traits are each on separate chromosomes that sort independently. You hypothesize that the genes for these traits are completely linked on the same chromosome and that they are all inherited together. 1.You cross 100 plants that are true-breeding for red flowers, hairy leaves, and petal veins (P1) with 100 plants that are true-breeding for purple flowers, smooth leaves, and no petal veins (P2). 500 plants of the F1 generation all have red flowers, hairy leaves, and petal veins. What does this tell you about the linkage between these genes? P1 P2 Purple Petals Smooth Leaves Veins Absent…arrow_forwardA researcher studied six independently assorting genes in a plant.

- 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_forward(d) Scientists believe that the yellow fern arose from hybridization with another fern on the island. Create a diagram of this hybridization that tracks the origin of the chromosome number in the yellow fern.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?

- 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.arrow_forwardDuring 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_forwardPls help with below homwork.arrow_forward
