What is the difference between variation and mutation

The other causes of genetic variation are gene flow, genetic drift, random mating, and random fertilization. Germline mutations and gene flow may introduce new genes to the population.

Genetic recombination, random mating, and random fertilization cause the reshuffling of alleles. Figure 4: Morphological Variation of Dogs. Environmental variation arises due to the effect of environmental factors such as diet, light, moisture, temperature, minerals, exposure, climate, culture, and lifestyle.

That means the phenotype of an individual is determined by the environment. The most precise example of environmental variation is the difference of phenotypes between identical twins. The morphological variation of dog due to genetic variation is shown in figure 4. Mutation: A mutation is a permanent alteration in the nucleotide sequence of a gene or a part of a chromosome. Variation: Variation is any difference between individuals or group of individuals belonging to a particular species.

Mutation: A mutation may affect a single individual. Variation: Variation can be seen in a group of individuals. Variation: Variation can occur due to mutations, genetic recombination, gene flow, genetic drift, random mating, random fertilization, and environmental factors.

Mutation: Hereditary mutations and acquired mutations are the two types of mutations. Variation: Genetic variation and environmental variation are the two types of variation.

Mutation: A mutation causes an alteration of a genotype in an individual. Mutation and variation are two causes of evolution. A mutation is an alteration of the nucleotide sequence of a gene or part of a chromosome. Mutations can be either hereditary or acquired. Mutations cause genetic variation among individuals of a particular population. Variation is any difference between individuals in a population. Other than mutations, genetic recombination, gene flow, genetic drift, random mating, random fertilization, and environmental factors cause variations.

The main difference between mutation and variation is the influence of each factor towards evolution. National Library of Medicine. National Institutes of Health, n. Available here. What is genetic variation. Origins of genetic variation Genetic variation is the difference in DNA sequences between individuals within a population.

What are mutations? Figure 1 Mutations are the original source of genetic variation. University of California Museum of Paleontology. Figure 2 Recombination contributes to human genetic variation by shuffling parental DNA and creating new combinations of variants. Image source: Creation Wiki. For a discussion on the sources of variation within a population see this chapter in An Introduction to Genetic Analysis. Or maybe it's a circumstance where I have the genes in the order ABC and you have them in the order of ACB because you have an inversion in that.

Those don't have to be pathological. In fact, most of them won't be, but it's a different kind of variation that in some instances may be playing a role in disease risk. Francis S. Collins, M.
