Explanation:

Gene therapy is a scientific technique that modifies a person's genes to cure disease. It can work by several mechanisms: Replacing a disease-causing gene with a healthy copy of the gene. Inactivating a disease-causing gene that is not functioning properly. Gene therapy when performed in germline cells becomes permanent and is transferred to the next generation. Somatic cells and adult stem cells are just like vegetative cells which do not help in passing genetic materials on to the offspring.
