Which of the following is an example of a method of asexual reproduction?

Fission is a method of asexual reproduction where an organism divides into two or more parts, each of which can grow into a new organism. This process is common in simpler organisms such as bacteria and certain protozoa. During fission, the genetic material is duplicated, and the parent organism splits, allowing for the creation of genetically identical offspring without the need for mating or combination of genetic material from two parents.

In contrast, the other options involve either sexual reproduction or principles of inheritance. Pollination and cross-fertilization are both processes involved in sexual reproduction, where genetic material from two parent organisms combines to produce offspring. Mendelian inheritance refers to the patterns of inheritance that are characteristic of organisms reproducing sexually, based on the principles outlined by Gregor Mendel. Therefore, fission stands out as the sole method of asexual reproduction in this context.
