The Bombay phenotype is important not only in solving paternity cases, but it also has important implications for blood transfusions involving people with this condition. The issue is that individuals can make antibodies against foreign blood cell molecules not in their own bodies. From which donors can Bombay individuals safely receive transfusions, and to which recipients can they donate their own blood

i think that it is plants

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).
