what is the difference between sexual reproduction and asexual reproduction
Answers
Answer:
Asexual reproduction:
A method of reproduction, usually present in lower animals and plants where progenies are produced from a single parent without the formation of gametes and fertilization. Example: division of bacteria by binary fission, budding of Hydra and yeasts, and vegetative reproduction in plants.
Sexual reproduction:
A method of reproduction where the progenies are produced by two parents of separate sexes. These parents produce morphologically and sexually different gametes. The union of gametes results in the formation of zygote. The zygote develops into new progeny.
Answer:
Asexual Reproduction:
1. It occurs in lower invertebrates and lower chordates and plants with simple organisations.
2. It is always uni-parental.
3. Gametes are not formed.
4. No fertilization.
5. It involves only mitosis
6. Daughter organisms are genetically identical to the parent.
7. Multiplication occurs rapidly.
8. Since there is no variation, so it does not contribute to evolution of the species.
Explanation:
Sexual Reproduction:
1. It occurs almost in all types of animals and mostly in higher plants.
2. It is usually bi-parental.
3. Gametes are always formed.
4. Fertilization takes place.
5. It involves both meiosis and mitosis.
6. Daughter organisms genetically differ from the parents.
7. Multiplication is not as rapid as in asexual reproduction.
8. Since there are variations, so it contributes to evolution of the species.
