The researchers participating in the experiments described above were assigned to conduct new experimentation, also on Leigh syndrome-positive mouse specimens. As a precursor step, it was decided to create a new population of Leigh syndrome-positive mice. What would be the option most likely to be successful in creating this population

Induction of intentional mutations in the mitochondria of pre-fertilization ova

Explanation:

Leigh syndrome is a neurological disorder which affects the motor and mental state of organisms. The Mitochondria is known as the power house of the cell due to its production of energy for use by various cells in the body. Most neurological problems affect the motor and mental state as a result of a mutated mitochondrion. This explains why Induction of intentional mutations in the mitochondria of pre-fertilization ova Is correct.
