Question

Quizplus · Accepted Answer

Genetic variation refers to differences in the genotypes of individuals within a population. These differences can arise due to a number of factors, such as mutation, recombination, and gene flow. The inheritance of alleles accumulated during an individual's lifetime is not a major source of genetic variation, as these changes typically occur in somatic cells and are not passed on to offspring. Similarly, the accumulation of mutations in somatic cells does not contribute significantly to genetic variation, as these changes are not passed on to offspring. Finally, asexual reproduction does not generally result in the formation of new combinations of alleles, as only one parent is involved in the process.
