Human genetic variation Structural variation is the variation in structure of an organism's chromosome. Structural variations, such as copy-number variation and deletions, inversions, insertions and duplications, account for much more human genetic variation than single nucleotide diversity.

What is a mutation? Genetic variation is a term used to describe the variation in the DNA sequence in each of our genomes. Genetic variation is what makes us all unique, whether in terms of hair colour, skin colour or even the shape of our faces. There are lots of different mutations that can occur in our DNA.

What is 'Variability' DEFINITION of 'Variability'. The extent to which data points in a statistical distribution or data set diverge from the average or mean value.Variability also refers to the extent to which these data points differ from each other. There are four commonly used measures of variability: range, mean, variance and standard deviation.The risk perception of an asset class is directly proportional to the variability of its returns.here are four commonly used measures of variability: range, mean, variance and standard deviation.

- Definition of Measure of Variation. Measure of variation is a measure that describes how spread out or scattered a set of data. It is also known as measures of dispersion or measures of spread. There are three measures of variation: The range, the variance, and the standard deviation.

variation Variation resulting from the appearance of mutations is called variation through mutation while that conditioned by subsequent recombination of genes as a result of interbreeding is called variation through recombination.roup variation includes the differences among aggregates of any rank—from differences among small groups of individuals within a population to differences among the kingdoms of living nature (animals and plants). In essence, the entire taxonomy of organisms is constructed on the comparative study of group variation.

What Is Genetic Variation? - Sources, Definition & Types Your genes have alleles, which are different forms of the same gene. Alleles are like a code for your body that determine hair color and eye color, height, and other genetic features. Genetic variation is the variation in alleles and genes, both within and among populations. Think of a population as a family unit. Within your family of closely-related individuals there is genetic variation.

Genes and Genetic Inheritance Genetic variation is a change in the genes that occur in organisms in a population. This variation typically occurs through DNA mutation, gene flow (movement of genes from one population to another) and sexual reproduction.

- Discrete variation refers to differences in characteristics that have a defined form. You can think of it as being either/or. For example. Your earlobes are either attached or they are not. Or whether or not you can roll your tongue.

Genetic variation Genetic variation is a fact that a biological system – individual and population – is different over space. It is the base of the genetic variability of different biological systems in space.Genetic variation is based on the variation in alleles of genes in a gene pool.It occurs both within and among populations, supported by individual carriers of the variant genes. Genetic variation is brought about by random mutation, which is a permanent change in the chemical structure of a gene.utations are likely to be rare and most mutations are neutral or deleterious, but in some instances the new alleles can be favored by natural selection. Polyploidy is an example of chromosomal mutation. Polyploidy is a condition wherein organisms have three or more sets of genetic variation (3n or more).

- Discontinuous and Continuous Variation. Variation is all the differences which exist between members of the same species. There are two kinds of variation; continuous and discontinuous.You should be able to give some examples of each. Continuous variation is variation that has no limit on the value that can occur within a population. A line graph is used to represent continuous variation. Discontinuous variation is variation that has distinct groups for organisms to belong to. A bar graph is used to represent discontinuous variation.

What is the source of variation within and among species? The original source of all variations in genetic makeup is genetic mutation. Mutations cause differences in genes which enter the overall gene pool of a given species, and then are passed among individuals. This happens within species, as well as among species according to evolution. bogieaggie · 8 years ago.

What is genetic variation? 1 Individuals of a species have similar characteristics but they are rarely identical, the difference between them is called variation. 2  Genetic variation is a result of subtle differences in our DNA.  Single nucleotide polymorphisms (SNPs, pronounced ‘snips’) are the most common type of genetic variation amongst people.

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

- The Coefficient of Variation is a ratio showing the degree to which individual points of data in a sample deviate from the mean. It is calculated by taking the standard deviat … ion of the sample and dividing that by the mean of the sample.
