Question

Plants produced by _ _ _ _ _ are genetically identical to the parent plants.
A) Sexual reproduction
B) Vegetative reproduction
C) Both A and B
D) None of these

Answer 1

Sexual reproduction is a process where two (n) haploid gametes such as sperm and egg are combined to form a (2n) diploid zygote which later develops into a new organism. While in vegetative reproduction new plants are developed from the small part of the parent plant.

Complete answer:
Option A: In sexual reproduction, two haploid gametes are combined to form one diploid zygote, in that case, variation occurs due to cross-linking of chromosomes so progeny cannot remain identical to the parent. Hence Option A is incorrect.
Option B: Vegetative reproduction is a specialized type of asexual reproduction in which new plants are developed from the small parts or fragments of the parent plant. Because of this, no genetic modification happens and the new plant remains genetically identical to the parent plant. Hence Option B is correct.
Option C: Option A is incorrect because genetic modification occurs in sexual reproduction. Hence Option C is incorrect.
Option D: Vegetative reproduction is the correct option given in option B. Hence Option D is incorrect.

Thus, the correct answer is Vegetative reproduction (option B).

Note: In plants, vegetative reproduction can happen via two ways,
-Natural vegetative propagation - It occurs naturally and does not require any human interference.
-Artificial vegetative propagation - It is carried out by humans and there are various methods - grafting, tissue culture, layering.
