Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A	True
B	False

Explanation:

Detailed explanation-1: -A genetically diverse population of individuals is more likely to survive than a population of individuals with similar genetic makeup. Variation allows some individuals within a population to adapt to the changing environment and natural selection allows the expression of those beneficial traits to persist.

Detailed explanation-2: -Variation improves the survival rate of species as it helps the individual organisms adapt based on altering environmental conditions. Variants formed due to environmental concerns form the basis for evolution.

Detailed explanation-3: -It is necessary for the survival of species as only then will the species have the adaptability to survive in rapidly changing external conditions. Any variation which is suitable for the particular niche is selected by nature during its process of evolution. This is spread over several generations.

Detailed explanation-4: -All variations in a species do not have equal chances of survival. Some of the variations may be so drastic that the new DNA copy cannot work with the cellular apparatus it inherits. Such, a newborn cell dies soon.
