This chart shows a portion of a dichotomous key. Dichotomous Key A dichotomous key is shown. 1 splits into 3. 3 splits into organism X and 9. 9 splits into 10 and organism Z. Which relationship can be determined from this dichotomous key? Organism X and organism Z have at least one observable trait in common. Organism Y has at least one observable trait in common with organisms X or Z. Organism X is in a different phylum than organism Y. Organism Z is genetically closer to organism X than to organism Y.

"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."
