en.wikipedia.org/wiki/Genetic_variation

Genetic variation means that biological systems – individuals and populations – are different over space. Each gene pool includes various alleles of genes. The variation occurs both within and among populations, supported by individual carriers of the variant genes. Genetic variation is brought about, fundamentally, ...

Genetic variation. Without genetic variation, some of the basic mechanisms of evolutionary change cannot operate. There are three primary sources of genetic variation, which we will learn more about: Mutations are changes in the DNA. A single mutation can have a large effect, but in many cases, evolutionary change is ...

Feb 4, 2015 ... 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. Individuals of a species have similar characteristics but they are rarely identical, ...

Understanding human genetic variation. □ Homo sapiens are a relatively young species. ▫ We have not had much time to develop genetically and produce variations. □ We each have approximately 3x109 base pairs of. DNA. ▫ No two people, except for identical twins, are genetically identical. ▫ Any two ...

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. Consequently, genetic variation is often considered an advantage, as it is a form of preparation for the ...

Sep 4, 2017 ... Definition. In genetic variation, the genes of organisms within a population change. Gene alleles determine distinct traits that can be passed on from parents to offspring. Gene variation is important to the process of natural selection. The genetic variations that arise in a population happen by chance, but the ...
