Final answer:
Genetic engineering or genetic modification was used to produce the new type of corn by introducing DNA from an unrelated species to the DNA of the corn, creating a transgenic plant with new traits.
Step-by-step explanation:
The process used to produce the new type of corn is genetic engineering or genetic modification. Through this process, DNA from an unrelated species is introduced to the DNA of the corn to create a transgenic plant. Transgenic plants have received recombinant DNA from other species, resulting in new traits. In this case, foreign DNA was added to the corn to produce a new type of corn with desired characteristics.
