NEET BIOLOGY

Detailed explanation-1: -Genetic variations that alter gene activity or protein function can introduce different traits in an organism. If a trait is advantageous and helps the individual survive and reproduce, the genetic variation is more likely to be passed to the next generation (a process known as natural selection).

Detailed explanation-2: -Genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population.

Detailed explanation-3: -Genetic variation describes naturally occurring genetic differences among individuals of the same species. This variation permits flexibility and survival of a population in the face of changing environmental circumstances.

Detailed explanation-4: -Explanation: Genetic diversity with more variation, it is likely that some individuals in a population will possess variations of alleles that are perfectly suited for the environment. Those individuals are more likely to survive to produce offspring bearing that allele.

Detailed explanation-5: -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.
