You are on a clinical rotation at a local hospital and are
shadowing Nurses and hanging out at the nursing station. One of the
nurses who had just came out of the restroom from his third or
forth trip to the restroom collapsed at his desk. He has been
looking very pale and has been losing weight. You run to get the
attending physician. The physician took one look and said something
that sounded like "see dif" to the nursing instructor. She said he
has been taking antibiotics for a nasty sinus infection. You are
asked to prepare a written report on his condition, but are afraid
to ask what it is. Where do you look first? What is it? How is it
spread? Why is it hard to kill? Who is most affected by it?

In your own words, define each level of prevention.
Mammograms, which are x-rays used to detect breast cancer, are a classic example of secondary prevention. Do mammograms prevent breast cancer? Why or why not? What is the point of screenings such as mammograms?
Give 3 examples of interventions at each level of prevention (that are NOT listed on the website/chart above). Be specific about what intervention you are discussing and what disease it will prevent.

In fruit flies, a grey body is dominant to a black body, and normal wings are dominant to vestigial wings. Flies are heterozygous for both grey bodies and normal wings were crossed with flies that had black bodies and vestigial wings. The following results were obtained:
Phenotype | Number of flies |
Grey body/Normal wings | 482 |
Black body/Vestigial wings | 472 |
Grey body/Vestigial wings | 103 |
Black body/Normal wings | 92 |
The results indicate that the genes for wings and body color are on the same chromosome. The recombinant offspring are a result of crossing over.
How many map units (expressed as a percentage to the nearest whole number) apart are the two genes?
