Explanation:
Asexual reproduction involves one parent and produces offspring that are genetically identical to each other and to the parent. Sexual reproduction involves two parents and produces offspring that are genetically unique.

Answer:
Sexual reproduction involves the fusion of male and female gametes whereas asexual reproduction does not require male and female individuals and no fusion of gametes takes place.
Explanation:
Asexual Reproduction:
- Sexual reproduction occurs in prokaryotic bacteria as well as certain eukaryotic unicellular animals, lower invertebrates, and plants.
- It has one parent.
- No gametes are produced.
- Parents' somatic cells are involved.
- There is no fertilisation.
- No reproductive organs are involved.
- Only mitosis-type cell division takes place.
- Genetically speaking, the offspring and the parent are identical.
- Only one parent's traits are passed on to the next generation.
- The genes and genetic material are simply replicated and passed on to new generations from the parent.
- The process of multiplication is quick and takes less time.
- The number of offspring born might range from two to numerous.
- Insignificant in terms of evolution.
- Different methods of asexual reproduction include bacterial fission, fragmentation, spore creation, and hydra bud development.
Sexual Reproduction:
- Sexual reproduction occurs in practically all multicellular creatures, including humans, animals, and higher plants.
- It is bi-parental.
- It produces gametes.
- It involves parental germ cells.
- Fertilization occurs.
- The presence of completely developed reproductive organs.
- Cells divide through both meiosis and mitosis.
- Genetically, the offspring will differ from the parents.
- Both of the parents' traits are inherited.
- To create a new set of genetic material, the genetic material from both parents is mixed together.
- The process of multiplying takes longer and is not as quick.
- The number of children born is significantly less.
- In the population, it has evolutionary relevance.
- Different methods of sexual reproduction include conjugation, external fertilisation, and syngamy.
