1. Animals that reproduce asexually include planarians, many annelid worms including polychaetes and some oligochaetes, turbellarians and sea stars. Many fungi and plants reproduce asexually.
2. Internal fertilization is the process when the syngamy (union of male and female gamete) occurs inside the female body after insemination using copulation. In contrast, External fertilization is the syngamy outside the female body, that is in the outer environment especially in water bodies.
3. Reproduction may be asexual when one individual produces genetically identical offspring, or sexual when the genetic material from two individuals is combined to produce genetically diverse offspring.
4. An advantage of this is that they can produce many bacteria very quickly. A disadvantage is that all of the bacteria are genetically identical.
5. Animals such as human beings, cows and dogs which give birth to young ones are called viviparous animals. Animals such as hen, frog, lizard and butterfly which lay eggs are called oviparous animals.
