| Asexual Reproduction | Sexual Reproduction |
|---|---|
| Only one parent is required. | Two parents are needed. They mate and produce the offspring. |
| Regeneration, fission and budding are some of the process through which cells divide. | Meiosis is the process by which the cells divide. |
| The offspring will also have a genetic disease if the parents have it i.e. no variation. This is its disadvantage. | Two organisms and a lot more energy is required. These are its disadvantage. |
| Spore formation, budding, vegetative reproduction, fragmentation are some of the types. | Conjugation and Syngamy are some of the types. |
| The advantage of this method is time efficiency, and requires less energy. | The advantage of this method is variation which produces unique organisms |
| Chance of variation is less. Mutation is less frequent. | Genetic variation takes place in every new organism. Leads to evolution |
| Sex cell or gametes are not formed. | Sex cell or gamete formation occurs |
| Lower organisms make use of this method | Higher vertebrates and invertebrates use this method |
| The unit of reproduction can be the whole parent body or a single somatic cell | Unit of reproduction is a gamete |
| The time taken is short for this type of reproduction. | This form of reproduction can take numerous months |
