Variation, a term in genetic science, refers to a genetic change that causes differing characteristics between organisms in a certain species. Much of the variation within and between species is due to differential regulation of genes and alleles. Gene alleles determine distinct traits passed on fro

The two main sources of genetic variation are mutations and recombinations of genes as a result of sexual reproduction. A mutation is a permanent change in the DNA within a gene.

Natural variations, also known as genetic variations, are mutations that randomly occur during sex cell division. These variations lead to different phenotypes that change an offspring's ability to survive and reach sexual maturity.

In biology, producers are organisms that produce organic compounds for the entire ecosystem. These organisms are at the beginning of the food chain; they can produce nutrients and compounds that other organisms can utilize.

Genetic variation generally refers to the differences in genes between individual members of a population, or the frequency in which the various gene types are expressed. Genetic variation is incredibly important for the survival and adaptation of a species, as it helps in terms of natural selection

Biology is important because it allows people to understand the diversity of life forms and their conservation and exploitation. Through various biological disciplines, people obtain knowledge about life and living organisms, including the origin, growth, evolution, structure, distribution and funct

Genetic variation is the result of mutation, gene flow between populations and sexual reproduction. In asexually reproducing organisms, some genetic variation may still result from random mutation.

A variation order is a change, often in construction, that modifies all or part of an existing order. Many construction projects undergo changes, especially after the beginning of building, and the cost impact on a construction project with a variation order can be costly.

Cultural variation refers to the differences in social behaviors that different cultures exhibit around the world. What may be considered good etiquette in one culture may be considered bad etiquette in another.

The term "direct variation" refers to a mathematical correlation between two variables where one variable can be represented as a constant multiple of the other unknown quantity. It is also known as a "direct proportion."
