Final answer:
The term 'Fission' is associated with asexual reproduction, where one organism produces identical offspring without genetic exchange, unlike sexual reproduction.
Step-by-step explanation:
The term associated with asexual reproduction but not sexual reproduction is C. Fission. Asexual reproduction is a process where one individual produces genetically identical offspring without the combination of genetic materials from two different individuals. This process includes methods like fission, budding, and fragmentation. On the other hand, sexual reproduction typically involves the fertilization of an egg by a sperm, leading to genetically diverse offspring. Therefore, fertilization is not associated with asexual reproduction, as there is no involvement of eggs and sperm.
