Cisgenesis refers to the genetic modification of an organism by inserting genes from the same species or a closely related one. Some possible synonyms for cisgenesis include intragenesis, adaption breeding, or homology-directed gene editing. Intragenesis implies that the transferred gene is derived from the recipient organism's own gene pool. Adaptation breeding suggests that genetic modification is aimed at improving the organism's adaptation to specific environmental conditions. Homology-directed gene editing typically refers to the precise replacement or modification of a gene without introducing new genetic material. Overall, these synonyms describe various approaches to genetic modification that limit the potential for unintended effects on the modified organisms.
