Detailed explanation-1: -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-2: -Which of the following best describes the genetic variation of a population? Genetic variation refers to the fact that different individuals of a population have different alleles of genes.
Detailed explanation-3: -It strengthens the ability of species and populations to resist diseases, pests, changes in climate and other stresses. Gene variations underpin their capacity to evolve and their flexibility to adapt.
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.
Detailed explanation-5: -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.
