Final answer:
Sexual reproduction usually results in fewer offspring as compared to asexual reproduction, which includes forms such as binary fission, budding, and fragmentation.
Step-by-step explanation:
Among the different forms of reproduction, sexual reproduction generally produces fewer offspring than asexual reproduction. This is because sexual reproduction involves the combination of genetic material from two different parents resulting in genetic diversity, which arguably benefits the survival of a species in changing environments. On the other hand, asexual reproduction forms like binary fission, budding, and fragmentation allow an organism to reproduce without a mate and can result in rapid population growth under suitable conditions. Parthenogenesis is also a form of asexual reproduction, where an unfertilized egg develops into a new individual. However, these offspring are generally genetically identical to the parent, which can be less advantageous in variable environments.
