- 11. Identify the process that enables cabbage, cauliflower, broccoli, kale, kohlrabi and Brussels sprouts to be produced from a common wild mustard plant. 12. Describe the process humans took to "transform" natural variations of the common wild mustard plant into the 6 vegetables shown above.What is the genotype of pure - breed round seeds ?. a .Rryy b . Rr c. Rrry d. RRFrom an agricultural point of view, discuss the advantages and disadvantagesof selective breeding. It is common for plant breeders to take two different, highly inbred strains, which are the product of many generations of selective breeding, and cross them to make hybrids. How does this approach overcome some of the disadvantages of selective breeding?
- Figure 4 shows the hybridization process between plant P and Q. b) What is process A?The aim of a research project is to produce a hybrid plant having resistance to disease. The disease resistance trait is cytoplasmically encoded. The parent plants which are chosen for the development of the hybrid are sexually incompatible. Which tissue culture technique will be used to produce a hybrid using these sexually incompatible parents.1. Which of the following has a genotype with homozygous purple flower and heterozygous tall plant. Consider purple is dominant over white and tall is dominant over short. A. Wwss B. WWSs C. wwSs D. WwSS 2. Which of the following has a genotype with heterozygous yellow kernel and heterozygous smooth kernel. Consider yellow is dominant over green and smooth is dominant over wrinkled. A. Ggww B. ggww C. GGWW D. GgWw
- Oh no! The F1 and F2 generation seed packet labels were mixed around. How would we know which seeds we planted by observing the color of the leaves? (Hint: What are the genotypes of the two generations? What color leaves do they produce in what ratios?)Why is hybrid seed so expensive to produce?Why is it so expensive to produce a hybrid plant seed?
- As an agriscientist, what techniques would you choose for creating a type of peach that could be grown in colder clit hybridization, genetic modification, or selective breeding? Why? << Read Less8) In just a few sentences, discuss why homoploid hybrids typically have a more difficult time forming barriers to reproduction with their parental species than an allopolyploid or autopolyploid. What is one example of a way that a homoploid hybrid plant can establish a barrier to reproduction with its parents?5a) It is generally considered that blue or purplish colored flowers attract bees as pollinators. Red flowers often attract birds such as hummingbirds as pollinators. Is this an example of prezygotic or postzygotic isolating mechanisms? Why? 5b) The graphs in your textbook show that the parental species are partially isolated by living at somewhat different altitudes in the mountains. In nature, the two parental species are also strongly (but not completely) isolated by using different pollinators (bees vs. hummingbirds). Is the presence of altitudinal separation combined with different pollinators likely to give more reproductive isolation in nature compared to each isolating mechanism alone? Why? 5c) Do the figures showing the F2 generation of the flowers suggest that these traits of flower shape and flower color are polygenic or due to single gene loci? Give a reason for your answer. 5d) Looking at the other graphs for this example that are shown in your textbook, is there any…
