Variation or mutation occurs within the DNA. It is a natural result of the replication process, or the copying of one DNA strand to make new DNA during reproduction. If the new mutation ends up making some kind of variation that does not kill the organism, then the variation will be passed on to new generations. This is how new traits are formed. When the variation is actually more useful than a trait that the organism's parents had, that new variation will be passed along as a survival trait.
Variation occurs in living organisms due to differences in genetic makeup, environmental influences, and random mutations during reproduction. It is essential for evolution as it allows for adaptation to changing environments and drives diversity within a species.

How do variation occur in asexually reproducing organisms?
Variation in asexually reproducing organisms can occur through mutations, which are random changes in the genetic material. Additionally, genetic recombination can occur through processes like gene transfer, leading to genetic diversity among the offspring. Environmental factors can also play a role in inducing variations in asexually reproducing organisms.
What are specific examples of variation within a species?
Human species, as in the variation in height.
What is veriation?
It appears there might be a typo in your question. If you meant "variation," it refers to differences or changes in something, such as characteristics, attributes, or outcomes, compared to a standard or a previous state. Variation can occur in a wide range of contexts, from genetics to statistics to quality control.
What term describes changes that within species?
The term that describes changes within a species over time is "microevolution." This involves genetic variations that occur within a population, leading to changes in traits or characteristics in response to environmental factors.
What two testable assumptions were the basis for Darwin's hypothesis?
Darwin made bold assumptions about heritable variation, the age of Earth, and relationships among organisms. First, in order for beak size and shape to evolve, there must be enough heritable variation in those traits to provide raw material for natural selection. Second, differences in beak size and shape must produce differences in fitness that cause natural selection to occur.
How and why variation occur in rate and sequence of development and learning?
how and why variation occur in the rate and sequence ot develpment and learning
How is variation related to?
The more variation there is in a group of specimens, the more evolution can occur between them.
Why is there variation?
the change that occur from parents in the offspring
How is variation related to evolution?
The more variation there is in a group of specimens, the more evolution can occur between them.
Why must a population have a genetic variation in order for natural selection to occur?
Without variation there is nothing to select from.
Which of the following is necessary for evolution to occur?
Genetic variation is necessary for evolution to occur, as it provides the raw material for natural selection to act upon. This variation can arise from mutations, genetic recombination, or gene flow.
Genetic variation is a necessary condition of which process?
Genetic variation is one of the conditions required for Natural Selection to occur.
Which of these is necessary for natural selection to occur genetic engeneering genetic variation asexual reproduction or enviormental stability?
Genetic variation is necessary for natural selection to occur. This variation provides the raw material for differential survival and reproduction, which drives the process of natural selection. Without genetic variation, there would be no differences for natural selection to act upon.
What characteristic within populations cause natural selection to occur?
Genetic variation. If there were no variation in the genes/phenotype then natural selection would have nothing to select from.
What characteristic within populations causes natural to occur?
genetic variation
Can natural selection occur without variation in a population?
no there is no genetic variation for natural selection to act upon
The degree of adaptation that can occur in a population is limited by?
the amount and kind of genetic variation in a population
