Detailed explanation-1: -Having variation within a species means that if the environment changes there may be individuals within the species more able to withstand the change and survive. There is usually extensive genetic variation within a population of organisms or a species.
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 within a species can result from a few different sources. Mutations, the changes in the sequences of genes in DNA, are one source of genetic variation. Another source is gene flow, or the movement of genes between different groups of organisms.
Detailed explanation-4: -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.
