What is an allele and how does it contribute to genetic variation in organisms?
An allele is a variant form of a gene that determines a specific trait. Alleles contribute to genetic variation in organisms by creating different combinations of traits through genetic recombination during reproduction. This variation allows for diversity within a population, which can lead to adaptations and evolution over time.
What is the relationship between a gene and an allele in genetics?
In genetics, a gene is a specific sequence of DNA that determines a particular trait. An allele is a variant form of a gene that can result in different expressions of that trait. Genes can have multiple alleles, which contribute to genetic diversity and variation in traits among individuals.
What mechanism is not a mechanism for genetic variation?
Mechanisms such as gene flow, mutation, genetic drift, and natural selection are all considered mechanisms for genetic variation. Non-genetic mechanisms, such as Lamarckian inheritance or acquired characteristics, are not considered valid mechanisms for genetic variation in the traditional sense.
What is the source of genetic variation?
Genetic variation arises from mutations, genetic recombination during meiosis, and gene flow between populations. Mutations are changes in the DNA sequence, while genetic recombination mixes genetic material from two parents during sexual reproduction. Gene flow occurs when individuals migrate between populations, introducing new alleles into a gene pool.
What are two sources of genetic variation?
Natural and Artificial Selection

Where is genetic variation stored in a population?
In the gene pool
Where is genetic variation stored in population?
In the gene pool
What also contributes to genetic variation?
The two main sources of genetic variation are gene shuffling and mutations. A mutation is a process wherein the structure of a gene is altered.
Which characteristic of DNA determines the variation of genetic expression in phenotypes?
The gene sequence of a DNA determines the variation of genetic expression in phenotypes.

What is a part of microevolution?
One example of microevolution is genetic variation within a population. This occurs because of the accumulation of small changes in the frequency of alleles (alternative forms of a gene) over generations.
What two different sources of genetic variation in a plant or animal population?
The main source of genetic variation is a large population with a large gene pool.
What are two sources of genetic variation?
