Meiosis happens during gamete formation; which is an important step of sexual … Different cells from the mass of cells undergo change to become various cell types and tissues. Mostly it occurs in unicellular organisms, e.g. One nuclei remains in the parent cell and other goes to the daughter. ; some by leaves like Bryophyllum, Begonia, etc. The plants produced by tissue culture are disease free. Asexual reproduction is a mode of reproduction by which offspring arise from a single parent, and inherit the genes of that parent only. Asexual reproduction is divided into fission, budding and fragmentation and regeneration. Budding: The method of asexual reproduction which takes place by the formation of a bud is called budding. So, the offspring are different from each other as well as from the parents. For example, some variant mosquito has developed resistance to DDT (Dichloro diphenyl trichloro ethane) which prevented their population from being wiped out. For eg: amoeba and paramecium.
