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).

the combining form means bone marrow or spinal cord. meio- "meiosis" myco- "mycosis" myelo- "osteomyelitis or myelogram" myo- "myositis";

the answer is: myelo- "osteomyelitis or myelogram"
