Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which statement below is correct about asexual reproduction and sexual reproduction?
A
Asexual reproduction and sexual reproduction both involve one parent
B
Sexual reproduction involves making clones and asexual reproduction creates unique offspring
C
Asexual reproduction creates clones and sexual reproduction creates unique offspring
Explanation: 

Detailed explanation-1: -Asexual reproduction generates offspring that are genetically identical to a single parent. In sexual reproduction, two parents contribute genetic information to produce unique offspring. Sexual and asexual reproduction have advantages and disadvantages-which is why some organisms do both!

Detailed explanation-2: -Asexual reproduction does not involve the formation and fusion of the gametes. Hence, fertilisation does not takes place. Vegetative propagation, a type of asexual reproduction involves the development of new individuals from the vegetative parts (root, stem and leaf) of the plant.

Detailed explanation-3: -Asexual reproduction is a type of reproduction in which a single parent produces a new progeny. The new progeny produced are genetically and physically identical to their parents, i.e., they are clones.

Detailed explanation-4: -Sexual reproduction is the process in which two parents are involved which produce two types of gamete i.e., male and female. The gametes fuse to form the zygote during fertilization. This is a compulsory event which allows the continuation of the species.

Detailed explanation-5: -Sexual reproduction is a mode of reproduction in which there is an involvement of two different sexes. Males produce male gametes and female produce female gametes. Both these gametes are haploid in nature as they are a result of meiotic cell division. Sexual reproduction also takes place in plants.
