What is variation short answer?

Variation can be defined as any difference between the individuals in a species or groups of organisms of any species. The mutation is the ultimate source of genetic variation, but mechanisms such as sexual reproduction and gene flow contribute to it as well.

What is variation and example?

Variation refers to the difference between two individuals of a species. Genetic variation arises due to mutation and recombination during meiosis. Examples of variation are different skin colour, eys, height, resistance to diseases, etc.

What is an example of variation in science?

Genetic variation results in different forms, or alleles?, of genes. For example, if we look at eye colour, people with blue eyes have one allele of the gene for eye colour, whereas people with brown eyes will have a different allele of the gene.

What is variation in natural science?

Variation is the difference between individuals from the same species. This variation can be inherited from one generation to the next. The individuals that are better suited (adapted) to their environment will survive to reproduce. This is called natural selection.

What is variation short answer? – Related Questions

What are types of variation?

There are two forms of variation: continuous and discontinuous variation.

What causes variation?

Major causes of variation include mutations, gene flow, and sexual reproduction. 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.

What is variation in evolution?

Variation is the difference in the characteristics of individuals in a population. They occur due to recombination and mutation, whereas evolution is the gradual process of change in inheritable characteristics of a population over several generations. Evolution occurs through natural selection.

What is variation and its importance?

Variation can be defined as the difference between the cells, organisms or group of organisms belonging to a particular species by environmental factors (phenotypic variation) or genetic differences (genotypic variations).

What is variation within a species?

Variation is the difference between individuals from the same species. This variation can be inherited from one generation to the next. The individuals that are better suited (adapted) to their environment will survive to reproduce. This is called natural selection.

What is variation and inheritance?

Inheritance is the process by which characters are passed on from parent to progeny; it is the basis of heredity. Variation is the degree by which progeny differ from their parents. Humans knew from as early as 8000-1000 B.C. that. one of the causes of variation was hidden in sexual. reproduction.

What are the 3 sources of variation?

The genetic diversity has three different sources: mutation, recombination and immigration of genes. Mutation is the driving force of genetic variation and evolution.

Where is most variation found?

The greatest diversity is found among populations in Africa, and gradually declines with increasing distance from the African continent, consistent with the Out of Africa theory of human origins.

What is variation controlled by?

There are two major causes of variation your genes and your environment. Apart from identical siblings, we’re born with a different combination of genetic information. This is the benefit of sexual reproduction to species – it creates variation within the species.

Why is variation important to a 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.

What are the advantages of variation?

  • Variations help some organism to fit better in the struggle for existence.
  • Variations help to adapt according to the changing environment.
  • Discontinuous variations produce new traits in the organisms.
  • Variation is essential for growth and it takes place during sexual reproduction.

What is variation in biology simple definition?

variation, in biology, any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation) or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation).

What is variation definition Class 10?

– Variations are the differences present between the individuals of the same species or different species. – The variation between different species is greater than that of the variation between the individuals of the same species.

What is variation in population?

Variation among populations refers to the level of differences between two or more populations. If two populations were genetically the same, then there would be no variation among the populations. The more different the populations are from each other, the greater the level of variation among the populations.

How is variation created in a population?

Solution : Occurrence of differences between organisms is called variation. New variation may arise during the process of DNA copying that already has variations accumulated from previous generations. Combining variations from two or more individuals would thus create new combinations of variations.

Why is genetic variation important in humans?

Human genomic variation is particularly important because a very small set of these variants are linked to differences in various physical traits: height, weight, skin or eye color, type of earwax, and even specific genetic diseases.

Which type of organism will have more variation?

1 Answer. Sexually reproducing organisms will show more variations as genetic material is exchanged between homologous pair of chromosomes during cross over.
