No, without variation, heredity and its branches of science are not possible.
- A branch of science that is involved in the study of genes and their variation as well as the heredity in all living organisms is known as Genetics.
- The population is not able to evolve without any genetic variation in response to the variables of changing environment and it will ultimately lead to enhance the danger of extinction. Even if the appropriate genetic variation is not available the population may likely be extinct soon. This way there would be no evolution of the population and they can all get eliminated due to any harsh disease.
- Genetics is a branch of biology concerned with the study of genes, genetic variation, and heredity in organisms.
Hence, variation play a significant role in the branch of science and heredity of living organism.

Inheritance, also known as heredity or biological inheritance is the transfer of traits from a parent to a progeny.
Explanations
- Genetic variation refers to the differences between the genomes of members of the same species.
- The genome is all the genetic information (all genes) of an organism.
- Mutations, which are changes in the genetic sequence of DNA, are the cause of genetic variation.
- Genetic variation is a term used to describe mutations in the DNA sequences of each of our genomes.
- Individuals of the species have similar characteristics but are rarely the same, the difference between them is called change.
