Fertilization: when the sperm reaches the egg begins to fertilize a new being, in the case of humans, the baby takes nine months to form.

Asexual reproduction: Is the process by which or organisms create a genetically similar or identical copy of it self without or combination of genetic material from descendent.

Asexual reproduction is a mode of reproduction by which offspring arise from a single parent, and inherit the genes of that parent only; it is reproduction which almost always does not involve meiosis, ploidy reduction, or fertilization. The offspring will be exact genetic copies of the parent, except in the specific case of automixis. A more stringent definition is agamogenesis which is reproduction without the fusion of gametes.

examples of asexual reproduction:

Mushrooms

Starfish

Flowers

Porifera

Anneils

Sea lily

Pamramecium

Sea urchin

Amoeba

Planaria

3. Aphids reproduce asexually have sex only for infections within the reason is that they have to digest siertas vacterias useful plants

4. Parthenogenesis is a form of reproduction based on the development of unfertilized female sex cells, which occurs with some frequency in flatworms, rotifers, tardigrades, crustaceans, insects, amphibians and reptiles, more rarely in some fish and, exceptionally, in birds .

5. the twins are two eggs are fertilized by sperm respective.
