Distinguish between mutation and variation.

Answer:
Difference Between Mutation and Variation. ... The slight difference in the sequence makes the one individual distinct from other, if the change is within the species of a population, it is the mutation, while if the change is within the population that is variation.
Answer:
Explanation:
The changes in the nucleotide sequence at the DNA level or in any one of the base pairs is known as mutation, while the genetic variation is how one individual of a species variate from another, variation can be due to changes in the nucleotide sequence like insertions, deletions, any genetic rearrangements or any environmental factors.
We all are aware of the DNA, RNA which are said as the genetic material and consist of the codes or bases A, C, G and T, and their combinations make the protein sequence. These proteins sequence are responsible for variations in the living organisms. The slight difference in the sequence makes the one individual distinct from other, if the change is within the species of a population, it is the mutation, while if the change is within the population that is variation.
Both terms are associated with each other and are said as the main reason for the evolutionary processes in any of the species, population or community. Mutations and variations also play a critical role for a group of organisms to adapt to the environment and is helpful in surviving. Though these processes have certain disadvantages too, as certain mutations and variations may lead to genetic disorders and severe diseases.
In this article, we will explore the difference between the two terms which are mutation and variation with a summary of them and their types.

BASIS FOR COMPARISON MUTATION VARIATION
Meaning
Mutation is the natural and permanent change, causing changes in the DNA sequence in any living organisms.
Variation or genetic variation is seen in an individual of any species, groups or population and is observed in genes as well as in alleles. By the process of natural selections, mutations may bring evolutionary changes.
It affects Mutations affect the single organisms.
Variations are seen in groups or populations of an individual.
Causing agent
Chemicals, ionising radiations, radioactive rays, chemical mutagens or x-rays. Gene mutations, crossing over, genetic recombinations, genetic drift, gene flow, environmental factors.
