In fruit flies, long wing (L) is dominant, vestigial wing (l) is recessive, gray body (G) is dominant, ebony body (g) is recessive. Two fruit flies were mated that were long-winged with gray bodies. The genotype of these two parental flies is LlGg ´ LlGg. What proportion of the offspring flies would have long wings and gray bodies?
A. All offspring would be long-winged with gray bodies.
B. Nine-sixteenths of the offspring would be long-winged with gray bodies.
C. Three-fourths of the offspring would be long-winged with gray bodies.
D. Seven-sixteenths of the offspring would be long-winged with gray bodies.
B. Nine-sixteenths of the offspring would be long-winged with gray bodies.

In what clinical situation is it most appropriate to use a broad-spectrum antimicrobial?
A. In an example of a pediatric otitis media (middle ear) infection. We can't properly test for the specific drug that would best eliminate the infection due to its location, so we use a broad-spectrum drug instead. B. In a case of viral meningitis. The infection spreads so quickly that we must treat it with an antibacterial drug as quickly as possible. We don't have time to determine which drug will work best, because the patient will die in the meantime. C. In a case of bacterial meningitis. The infection spreads so quickly that we must treat it with an antibacterial drug as quickly as possible. We don't have time to determine which drug will work best, because the patient will die in the meantime. D. In a case of Staphylococcus aureus skin infection. Since this microbe can be resistant to several types of drugs, we want to use one that has the broadest spectrum possible to treat this microbe-specific infection.
