Sample Question
A figure describes the evolution of drug resistance in HIV where the drug is a reverse transcriptase inhibitor. All 3 colored lines begin on the left axis at a point above 0 % of HIV resistance 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.
