Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population. ... Genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population.

How can variation help species?
Genetic variation in a group of organisms enables some organisms to survive better than others in the environment in which they live. Organisms of even a small population can differ strikingly in terms of how well suited they are for life in a certain environment.
Why do we need variation?
Different species have different characteristics from each other. ... This means that no two members of a species are identical. The differences between the individuals in a species is called variation. Variation helps a species to survive, by causing individuals of a species to be genetically and physically different.
Why is variation important in a species?
Having variation within a species means that if the environment changes there may be individuals within the species more able to withstand the change and survive. ... it produces variation in the offspring. the species can adapt to new environments due to variation, which gives them a survival advantage.
What is variation in population?
Genetic variation in a population describes the existence in that population of different alleles, or alternative forms, for a given gene. ... Phenotypic variation describes differences in the characteristics of individuals of a population.
How is variation created in a population?
The process of variation can be brought about as a result of any type of mutations in the genes. ... Mutation can create entirely new alleles in the population giving rise to variation. It can also arise by random mating and fertilization.
Why is population genetics important?
The fundamental importance of population genetics is the basic insights it provides into the mechanisms of evolution, some of which are far from intuitively obvious. ... As our knowledge of how genomes are organized and function has increased, so has the range of problems confronted by population geneticists.
What is variation and it's importance?
Variation is important because it causes evolution and is the basis of heredity. It is advantageous to a population as it enables few individuals to adapt to the environment changes thus, enabling the survival of the population.
What is variation and its importance?
Variations improve the chances of survival of a particular species on the onset of unfavorable conditions. ... Variation is the major source of species and environmental evolution wherein the more fit organisms replace the less fit organism from the environment they were earlier sharing.
Why are variations important how are variations useful for an organism on a population?
Variations are useful for an organism or a population in following ways: It increase the chance of survival. It provide the barrier to fight against the predator of the organism. It helps the organism to adapt the changing environment.
Why is variation not beneficial for the individual?
Variations give organisms an individuality of their own. In the absence of variation, there would be no science of heredity as all individuals of a race would be identical to one another in all aspects.
Why are mutations so important to living organisms?
The ultimate source of all genetic variation is mutation. Mutation is important as the first step of evolution because it creates a new DNA sequence for a particular gene, creating a new allele. Recombination also can create a new DNA sequence (a new allele) for a specific gene through intragenic recombination.
What does variation mean in statistics?
Variation is a way to show how data is dispersed, or spread out. Several measures of variation are used in statistics.
What is variation in a community?
A community changes when its constituent species change and/or when the frequency of species changes over time. ... It represents the change in the total or average phenotype of the ecosystem that can be explained by variation in fitness within species.
What is variation How is reason created in a population How does the creation of variation in a species promote survival?
Variations Promote the survival of the species as variations allow them to adapt and survive to the changing environment and connections. Different species have different kin of advantages depending on the nature of variation. (b) Gametes are produced through meiosis.
How is variation spread and promoted within population?
DNA mutation causes genetic variation by altering the genes of individuals in a population. Gene flow leads to genetic variation as new individuals with different gene combinations migrate into a population. Sexual reproduction promotes variable gene combinations in a population leading to genetic variation.
What is variation in gene expression?
Variation in gene expression constitutes an important source of biological variability within and between populations that is likely to contribute significantly to phenotypic diversity. Recent conceptual, technical, and methodological advances have enabled the genome-scale dissection of transcriptional variation.
