Which of the following is most likely an example of genetic drift resulting from the founder effect?

An example of genetic drift resulting from the founder effect, of the available answers listed below, would most likely be a situation in which a population commonly expresses traits that are otherwise rare in the species. An example of this might be an animal with longer limbs than other members of the same species - there have been real-life examples of this studied with lizards.

Explanation:

"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."
