Difference between mutation and variation

Main difference

The main difference between mutation and how the mutation is the changes in the nucleotide sequence at the DNR level, while the variation is an individual of species is different from another individual …

Mutation versus variation

A mutation is a change that occurs in the genome (genetic makeup) of an individual organism. The mutation can be spontaneous. They occur due to radiation, chemicals, and sometimes due to cigarette smoke. If a mutation is small, it can be beneficial, but if it is large, the organism may not survive to reproduce. On the other hand, variation is the change that occurs between a group of species. It can be genetic or environmental in origin. For example, when some people have different hair or eye color, etc. This change is considered a variance. Some types of mutations are very beneficial and have a positive impact on organisms. These mutations support the individual to adapt to environmental conditions. They help organisms to better adapt to new living conditions. But some mutations can be harmful and cause disease or disorder. For example, thalassemia and sickle cell anemia are the result of a mutation. Sometimes cancers also suffered due to mutational changes in genes. Unlike mutation, variation is always considered a positive change, as it helps to recognize one individual from another. It helps to change and outperform populations depending on the environment. Variations give to help the individual survive and produce different types of generations. Variation is the main pathway for the natural selection process because it removes the factor that prevents the path of variation. The variation can continue or stop in future generations. Sometimes, Cancers also suffered due to mutational changes in genes. Unlike mutation, variation is always considered a positive change, as it helps to recognize one individual from another. It helps to change and outperform populations depending on the environment. Variations give to help the individual survive and produce different types of generations. Variation is the main pathway for the natural selection process because it removes the factor that stands in the way of variation. Variation can continue or be interrupted in future generations. Sometimes cancers also suffered due to mutational changes in genes. Unlike mutation, variation is always considered a positive change, as it helps to recognize one individual from another. Helps to change and outperform populations depending on the environment. Variations give to help the individual survive and produce different types of generations. Variation is the main pathway for the natural selection process because it removes the factor that prevents the path of variation. The variation can continue or be interrupted in the next generations. The variations give to help the individual to survive and to produce different types of generations. Variation is the main pathway for the natural selection process because it removes the factor that prevents the path of variation. The variation can continue or stop for generations to come. Variations give to help the individual survive and produce different types of generations. Variation is the main pathway for the natural selection process because it removes the factor that prevents the path of variation.

Mutation Variation
Alteration of the nucleotide sequence in the genome of any organism or extrachromosomal DNA is called a mutation. Any change or small difference of one individual from another individual in a group is called variation.
To affect
Affects only one individual It can be seen in groups of populations of an individual.
Causative agents
Radiation (radioactive rays, X-rays), chemicals, cigarette smoke Environmental factors, genetic mutation, crossing, genetic recombination, genetic drift, gene flow,
Types
1. Fixed, stable, germline, inherited or chromosomal mutation
2. Acquired, somatic, dynamic or unstable mutation

What is a mutation?

The mutation is known as a spontaneous change that occurs at the level of the genome of an organism. It can occur in a germ line cell or somatic cell, but it can also occur in a gonadal or gamete cell. The mutation causes a change in the DNA sequence, which can be due to fumes, harmful radiation, environmental factors, or errors in DNA replication. Although the mutation during cell replication is recognized by the cell and resolves at that time, some mutations have the potential for damage and attachment. These fixed mutations are genetically transferred and affect positively, but some show harmful effects and cause disease, for example sickle cell anemia, thalassemia, and cancer. The inherited mutation is also called a chromosomal mutation, and it occurs in the sperm or egg. This genetic change is transferred to the new living and dividing cell of the new developing organism. The chromosomal mutation plays a larger role in genome change, as the changes occur during the meiosis process. Chromosomal mutations are of different types that can be structural abnormalities and numerical abnormalities. Numerical abnormalities are of two types: aneuploidy and polyploidy, while structural abnormalities have five types called inversions, deletions, translocations, and ring formation. There are also sex-linked mutations that are related to mutations in the sex chromosomes. Chromosomal mutations are of different types that can be structural abnormalities and numerical abnormalities. Numerical abnormalities are of two types: aneuploidy and polyploidy, while structural abnormalities have five types called inversions, deletions, translocations and ring formation. There are also sex-linked mutations that are related to mutations in the sex chromosomes. Chromosomal mutations are of different types that can be structural abnormalities and numerical abnormalities. Numerical abnormalities are of two types: aneuploidy and polyploidy, while structural abnormalities have five types called inversions, deletions, translocations, and ring formation. There are also sex-linked mutations that are related to mutations in the sex chromosomes. There are also sex-linked mutations that are related to mutations in the sex chromosomes. Chromosomal mutations are of different types that can be structural abnormalities and numerical abnormalities. Numerical abnormalities are of two types: aneuploidy and polyploidy, while structural abnormalities have five types called inversions, deletions, translocations, and ring formation. There are also sex-linked mutations that are related to mutations in the sex chromosomes. There are also sex-linked mutations that are related to mutations in the sex chromosomes. Chromosomal mutations are of different types that can be structural abnormalities and numerical abnormalities. Numerical abnormalities are of two types: aneuploidy and polyploidy, while structural abnormalities have five types called inversions, deletions, translocations, and ring formation. There are also sex-linked mutations that are related to mutations in the sex chromosomes. deletion, translocations and ring formation. There are also sex-linked mutations that are related to mutations in the sex chromosomes. deletion, translocations and ring formation. There are also sex-linked mutations that are related to mutations in the sex chromosomes.

What is variance?

The word “genetic variation” is used to show different characteristics between different organisms, how they differ from each other in terms of hair, nails, hands, color, body shapes, and so on. It reflects the DNA sequence that differentiates one genome from another. There are two important sources of variation: mutation and recombination. A mutation is a permanent alteration of the DNA sequence. New mutations occur when there is an error during DNA replication that is not corrected by DNA repair enzymes. It is only the error that is copied through DNA replication and fixed in DNA that is considered a mutation. The mutation can be beneficial to the body, harmful or neutral. Somatic mutations can accumulate in cells and, for the most part, without any damage. They can cause local changes in tissues like moles on the skin and can have serious effects like cancer. Recombination is the second source of genetic variation. Every human being has a mix of genetic material. This mixing occurs during recombination when homozygous DNA supports align and cross. Recombination efficiently shuffles maternal and paternal DNA, producing new combinations of variants in daughter cells.

Environmental variation, also known as variation, is seen in the population due to changes in the organism, while genetic variations are transferred from one generation to another. If the variation continues in generations and there is a slight difference in two organisms, then it is called continuous variation, while if the variation does not happen in the next generations, it is called discontinuous variation.

Key differences
  1. Mutation is the change in DNA, while variation can be in DNA or environmental.
  2. Mutation is the small or large level change, while variation is the change in the whole group.
  3. The mutation always causes changes in the genes, while the variation is the change in the genes or a general change.
  4. The causative factors of the mutation are cigarette smoke, radiation and chemicals, while the causative factors of various genetic changes and environmental factors.
  5. Mutation can be harmful or beneficial, while variation always has a positive impact.
  6. Stable and unstable are the types of mutation, while genetic variation and environmental variation are the types of variation.

Final Thought

It has been concluded that mutation and variation can vary from one gene to another and from one organism to another.
