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. Each fragment develops into a mature, fully grown individual.

What is asexual reproduction? Asexual reproduction is reproduction without sex. In this form of reproduction, a single organism or cell makes a copy of itself. The genes of the original and its copy will be the same, except for rare mutations. They are clones. The main process of asexual reproduction is mitosis. This type of reproduction is common among some single-cell organisms, for example, amoeba. Many plants also reproduce asexually. Types of Asexual Reproduction Binary fission
