Sample Question
The figure to the right describes the evolution of drug resistance in HIV where the drug is a reverse transcriptase inhibitor. Notice that all 3 colored lines begin on the left axis at a point above 0 % of HIV resistant to 3TC. What is the significance of the observation that the number is greater than zero?

Apparently prior to the appearance of HIV in human populations, some humans had a characteristic that pre-adapted them to survive upon exposure to the virus.

In a population of HIV viral particles, a small proportion are of a genetic type that they are not effected by the drug.

As soon as the human population became exposed to HIV, some individuals adapted to the situation.

That is probably just a sampling error.

Upon exposure to the drug, some viral particles adapt by mutation to a form that can thrive in the face of the drug.

Sample Question
The "biological species concept" offers us a practical way to distinguish species of organisms and to assign individuals to one taxon or another. In order to catalog individuals as being members of one species or antoehr using this concept focuses on

Morphological differences distinguishing the species

Differences in the geographic distribution of the species

The ability of individuals to successfully breed with each other

Sample Question
As a consequence of size alone, organisms that are large tend to have larger brains than organisms that are small. However, some organisms have brains that are considerably larger than expected for an animal of their size. Data for 14 bird species are listed below. Graph the data and then, based on the data, determine which of the statements below is most reasonable. Deviation from expected brain size, that is the brain size based on body mass alone. (Negative values indicate grain sizes smaller than expected; positive values indicate brain sizes larger than expected.) -1.8 1.2 3.2 -2.4 0.0 -2.0 2.3 2.0 -1.0 -2.1 0.3 3.0 1.3 0.7 Mortality rate 0.9 0.8 0.6 0.9 0.7 0.5 0.6 0.6 0.4 0.7 0.8 0.3 0.3 0.4

Apparently because of the costs associated with increase brain size, there is an upper limit as to how large bird brains can evolve.

Larger than expected brain sizes are associated with lower mortality rates. (This could be the result of large-brained birds having an increased intelligence that gives them an advantage in finding food, or escaping predators, though the data do not address this.)

There is no correlation between brain size and mortality rate. (This could be because of conflicting selective pressures. For example, any advantage of having a relatively large brain, perhaps increased intelligence, may be counter balanced by a disadvantage of having a relatively large brain.

Birds with brain sized that are larger than expected have relatively high mortality rate. (This could result from the metabolic costs associated with maintaining that relatively large brain, though the data do not address this.)

Sample Question
Among "Gypsies" (the Roma) there is a mutation (1267de1G) that is particulary common. Individuals identified as Roma live at varioous locations in the Old world. Statistical analysis dates the mutation's arrival in the population to ~1000 years ago. The mutation is otherwise found only in families of Indian or Pakistani origin, supporting the theology that the Roma originated there. One would predict that the reason for its much higher incidence among the Roma than among Indians or Pakistani is

Genetic drift is the small populations of the Roma

Gene flow from India and Pakistan to the various parts of the world where the Roma live

Higher levels of inbreeding in the small populations of the Roma than are found in the much larger breeding populations in India or Pakistan

Tow of the above are liely explantions

None ofthe above is correct
