Many organisms can reproduce asexually through mitosis, while other organisms reproduce sexualy, and their cells carry out meiosis to form gametes. in a situation where an organism falls pray to many efficient predators, which of these processes would be most beneficial to a species?

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).
