Answer:
The correct answer will be- genetic engineering
Explanation:
Genetic engineering is a group of techniques employed to manipulate the DNA of the organisms which can help regulate the phenotype of the organism.
The genetic engineering aims at selecting the desired trait to be passed on to the progenies eliminating the harmful traits so as to benefit the organisms. The scientist selects the genes of the trait and then clone it to introduce it to the species.
Since the scientist can select the desired trait through techniques and manipulates the DNA therefore genetic engineering is the correct answer.
