Question

what are the importance of variation among individuals

Answer 1

The Genetic Variation in a Population Is Caused by Multiple Factors. 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

Answer 2

Evolution and Adaptation to the Environment. Variation allows someindividuals within a population to adapt to the changing environment. Because natural selection acts directly only on phenotypes, more geneticvariation within a population usually enables more phenotypic variation.
