25. Answer the following questions based on the facts and inferences related to natural selection that we discussed in class, as well as the simulations you performed with the Evodots lab. If individuals vary, and variation affects survival and reproduction, and variation is heritable: there will be natural selection resulting in evolution. there will be no natural selection, but there will be evolution due to natural selection. there will be natural selection, but it will not result in evolution. there will be no natural selection, and there will be no evolution due to natural selection. 24.

1.) Natural Selection: Of the three genotypes (AA, Aa, and aa), which of the three genotypes will be selected for under the current conditions? In other words, which of the three genotypes will increase in frequency? What if medical science were able to hold off the effects of AIDS for indefinite periods of time so that it became common for people with AIDS to live long enough and well enough to have children. What would this do to the frequency of the resistance allele and the incidence of AIDS? Support your answer. 2.) Even though anti-HIV drugs may prevent evolution towards resistance, can you justify not using anti-HIV drugs if they are available? Your response should consider scientific and ethical perspectives.

1. What is true of natural selection? The only way to eliminate harmful mutations is through natural selection. Mutations occur at random; natural selection can preserve and distribute beneficial mutations. Natural selection creates beneficial mutations. Natural selection is a random process. All changes saved
