I would say 1 and 4 are the best answers. GMO crops are clones (genetically identical) so it reduces the genetic diversity making crops susceptible to new diseases.
Answer:
The effect of SNP on individual's susceptibility to disease opens a way for a field of pharmacogenomics, which helps to focus treatment of diseases using the differences in the genomic composition.
Explanation:
Pharmacogenomics is a field which reflects relationship between the genetic make-up with the response to therapeutic intervention. This enable an individual treatment pattern according to the variation in genetic make up.
Neuroimaging or brain imaging is the use of various techniques to either directly or indirectly image the structure, function/pharmacology of the nervous system. It is a relatively new discipline within medicine, neuroscience, and psychology.
