Scientists have incorporated a barley gene into a type of rice and produced rice plants that have much lower methane emissions. It is most likely that the scientists incorporated the barley gene into the rice, producing a new variety, using the process of .

The correct answer is "genetic engineering".

Explanation:

The missing options of this question are:

(1) selective breeding

(2) meiosis, followed by recombination

(3) genetic engineering

(4) sexual reproduction, followed by mitosis

The correct answer is option (3) "genetic engineering".

Genetic engineering is a modern technology that uses a DNA recombinant approach to alter the genetic material of an organism. In this case the genetic material of rice was modified by incorporating a new gene that is originated from barley. The transference of a gene from an organism to another is most easily achieved by genetic engineering technology.
