In Central and Northern California, the Red-legged Frog (Rana aurora) breeds from January to March. The closely related Yellow-legged Frog (Rana boylii) breeds from late March through May. Based on this information, which of the following is a scientist most likely to observe if these two species of frog are studied for multiple generations? The two species may experience convergent evolution due to differences in the timing of sexual activity.
The two species may experience divergent evolution due to differences in the timing of sexual activity.
The two species may experience adaptive radiation due to differences in the timing of sexual activity.
The two species may experience coevolution due to differences in the timing of sexual activity.

explanation:

ok

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."

did you fail the test? xd
