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

A	True
B	False

Explanation:

Detailed explanation-1: -Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism’s offspring).

Detailed explanation-2: -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-3: -Variation is essential Without differences between the individuals in a population, populations cannot change over time-that is, they cannot evolve. Some features must exhibit variability so that change is possible. This variation arises when novel genes are produced as mutations.
