Chapter 7, Problem 41P
In each of the following cross schemes, two true-breeding plant strains are crossed to make F1 plants, all of which have purple flowers. The F1 plants are then self-fertilized to produce F2 progeny as shown here.
| a. | For each cross, explain the inheritance of flower color. |
| b. | For each cross, show a possible biochemical pathway that could explain the data. |
| c. | Which of these crosses is compatible with an underlying biochemical pathway involving only a single step that is catalyzed by an enzyme with two dissimilar subunits, both of which are required for enzyme activity? |
| d. | For each of the four crosses, what would you expect in the F1 and F2 generations if all relevant genes were tightly linked? |

13. Practice Calculations: 3 colonies were suspended in the following dilution series and then a
viable plate count and microscope count was performed. Calculate IDF's, TDF's and then
calculate the CFU/mL in each tube by both methods. Finally calculate the cells in 1 colony by
both methods. Show all of your calculations in the space provided on the following pages.

- You have been hired as a public relations specialist to give invertebrates a good name. After all, they are much more than just creepy crawly bugs! Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.arrow_forwardUse the following tree diagram to answer Questions #8-10. 8) Which of the following two animals are the most closely related based on the tree to the left? a) Pig and camel b) Hippo and pig c) Deer and cow 9) CIRCLE on the tree diagram where the common ancestor between a hippo and a cow is. 10) Put a SQUARE on the tree diagram where the common ancestor between a pig and a peccary is.arrow_forwardExplain: Healthy Cell Function Overview→ Briefly describe how a healthy cell usually works: metabolism (ATP production), pH balance, glycogen storage, ion transport, enzymes, etc. Gene Mutation and Genetics Part→ Focus on the autosomal recessive mutation and explain: How gene mutation affects the cell.
