Asexual reproduction in liverworts: a caducous phylloid germinating. Asexual reproduction is a mode of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only; it does not involve the fusion of gametes and almost never changes the number of chromosomes.ragmentation is a form of asexual reproduction where a new organism grows from a fragment of the parent.

Asexual reproduction is a mode of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only; it does not involve the fusion of gametes and almost never changes the number of chromosomes.rganisms, both prokaryotes (the archaea and the bacteria), and eukaryotes (such as protists and unicellular fungi), reproduce asexually through binary fission; most of these are also capable of sexual reproduction. Another type of fission is multiple fission that is advantageous to the plant life cycle.
