Answer:
Gene Transfer
Step-by-step explanation:
Gene Transfer is a form of Genetic Modification aimed at creating new qualities that do not naturally exist in a species. In the question above this was done by introducing the genetic makeup of the Pacific Chinook salmon and the ocean pout into the genome of the Atlantic Salmon.
AquaAdvantage salmons have been engineered to grow faster than Atlantic Salmon. They achieve an average size of 4.5Kg in 16 to 20 months compared to an average time of 30 months for naturally occurring Atlantic Salmon to reach the same size.
