SEXUAL REPRODUCTION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
True or False:A scientist wants to use asexual reproduction to grow new potatoes because the new plants will have greater genetic diversity.
A
True
B
False
Explanation: 

Detailed explanation-1: -The potato plant undergoes asexual reproduction via vegetative propagation. Vegetative propagation is the reproduction process in which new plant offspring can be formed from vegetative parts of the plant like roots, stems, and leaves. Potato contains small eyes/tubers that give rise to leaves in them.

Detailed explanation-2: -In asexual reproduction new plants are obtained without production of seeds. It is a type of asexual reproduction in which new plants are produced from roots, stems, leaves and buds. Since reproduction is through the vegetative parts of the plant, it is known as vegetative propagation.

Detailed explanation-3: -Sexual reproduction generates more variations than asexual reproduction. This happens because of contribution of DNA from two parents with their own variations which produces a novel combination in the offspring. Though asexual reproduction produces variations which are less in number.

Detailed explanation-4: -Sexual reproduction allows for a greater genetic diversity through the process of Fertilisation. It involves the meiosis process which means a cell doubling its DNA, shuffling its genes and then dividing the shuffled DNA among four cells.
