1. It occurs almost in all types of animals and mostly in higher plants.
2. It is bi-parental.
3. Gametes are always formed.
4. Fertilization takes place.
5. It involves both meiosis and mitosis.
6. Daughter organisms are genetically different from the parents.
7. Multiplication is not as rapid as in asexual reproduction.
8. Since there are variations, so it contributes to the evolution of the species.
1. It occurs in lower invertebrates and lowers chordates and plants with simple organisations.
2. It is always uni-parental.
3. Gametes are not formed.
4. No fertilization or fusion of gametes occurs
5. It involves only mitosis.
6. Daughter organisms are genetically identical to the parent.
7. Multiplication occurs rapidly, of which prokaryotes such as bacteria are good examples.
8. Since there is no variation, so it does not contribute to the evolution of the species.
