Which of the following is true about asexual reproduction?
It results in offspring genetically identical to the parent.
It requires complex reproductive organs.
It requires fertilisation.
It involves two parent organisms.
It results in offspring genetically identical to the parent.
Asexual reproduction is a mode of reproduction where a single parent gives rise to new offspring without the involvement of gamete fusion or fertilisation. Consequently, the offspring are genetically and morphologically identical to the parent, often referred to as clones.

Think of asexual reproduction like a document photocopier: the output is an exact replica of the original document without any changes, whereas sexual reproduction is like mixing two different colors of paint to create a unique new shade.
M-I-T-O-S-I-S: M-akes I-dentical T-o O-riginal S-ame I-ndividual S-tructure.
2n тАФ The number of organisms produced after n cycles of binary fission.
The process relies primarily on mitotic cell division, where the parent's DNA is replicated and divided equally between the daughter cells. Unlike sexual reproduction, there is no meiosis or recombination, meaning the genetic material remains stable across generations.
Involves only one parent.
No meiosis or fertilisation involved.
Rapid method of multiplication.
Common in bacteria, yeast, and Hydra.
Energy-efficient (no need to find a mate).
Rapid population growth in stable environments.
Lack of genetic variation reduces adaptability to changing environments.
Budding in yeast.
Binary fission in Amoeba.
| Feature | Asexual | Sexual |
|---|---|---|
Requirement | One Parent | Two Parents |
Option B is wrong because asexual reproduction occurs in unicellular organisms lacking complex organs.
Option C is wrong because fertilisation is a hallmark of sexual reproduction.
Option D is wrong as it defines sexual reproduction.
A is correct тАФ Asexual reproduction results in offspring genetically identical to the parent.
Always remember that 'Asexual' = 'Absent of Gametes/Fertilisation', while 'Sexual' = 'Syngamy (Fusion of gametes)'.
