The allele b gives Drosophila flies a black body, and b+ gives brown, the wild-type phenotype. The allele wx of a separate gene gives waxy wings, and wx+ gives nonwaxy, the wild-type phenotype. The allele cn of a third gene gives cinnabar eyes, and cn+ gives red, the wild-type phenotype. A female heterozygous for these three genes is testcrossed, and 2,424 progeny (you could also use n=2,423) are classified as follows:
| cn+ · wx+ · b | 101 |
| cn · wx+ · b+ | 768 |
| cn · wx+ · b | 20 |
| cn+ · wx+ · b+ | 323 |
| cn+ · wx · b | 848 |
| cn · wx · b+ | 101 |
| cn · wx · b | 242 |
| cn+ · wx · b+ | 20 |
Calculate the recombinant frequencies for b-wx, b-cn, and wx-cn.
Which gene is in the middle: b, wx, or cn?

PREPARATION OF COMPETENT CELLS and TRANSFORMATION:
2a. We will be preparing competent MM294 (E. coli) cells using a chemical treatment of CaCl2. What are MM294 cells, why do we use them? Define “competent” cells and describe why/how CaCl2 makes cells “competent”. Why is “mid-log” phase important? Support your drawing with a cartoon of what cells “look like” before and after treatment.
2b. What does “heat-shock” do (in the transformation procedure)?
2c. What is LB? What does “LB” stand for and what is its role in cloning? What would happen if LB was NOT on the plates?

Assume that you have recently been hired as the special assistant to the chief executive officer (CEO) of your health care organization, Thunder Hospital. Your duty is to head up the new quality improvement department. Over the last year, the hospital has experienced substantial growth but is also facing a number of patient safety concerns, including a steady increase in medical errors and a 25% rise in hospital-acquired infections. Based upon what you have learned in this course, prepare a quality improvement plan to present to the CEO with strategies for addressing these issues.

53. Females are likely to mate with more than one male when
Select one:
a. resources can�t be monopolized, as in robins who eat worms.
b. only some males are able to get good territories.
c. predation on eggs or on young is high.
d. the male stays with the young and/or the eggs.
e. both c and d
54. In many species, females are certain of their parenthood; males are not. Eggs and live births require a larger investment of energy than do sperm. Therefore,
Select one:
a. Male success is more dependent than is female success on the number of times he mates.
b. Female success is more dependent than is male success on the number of times she mates.
55. In many species, females are certain of their parenthood; males are not. Eggs and live births require are larger investment of energy than do sperm. Therefore,
Select one:
a. Females tend to be more competitive; males tend to be more choosey.
b. Males tend to be more competitive; females tend to be more choosey.
c. Female competition results in weaponry.
