Explain which type of medicine the physician is practicing in the following scenario.

situation: dr. todd, a physician is seeing a patient mr. james.
dr. todd: "what seems to be ailing you sir? "
mr. james: "i have had a fever for several days with vomiting."
dr. todd: "i will need to draw some blood to test if you have a bacterial or viral infection. that will determine how i will proceed with your treatment."

the last one: artificial selection/genetic engineering

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).
