DNA is responsible in most organisms, but RNA is responsible for heredity and variation of a lot of viruses.
The two types of variation shown by living organisms are genetic variation, which is differences in DNA sequences among individuals, and phenotypic variation, which refers to observable traits or characteristics that vary among individuals.
Each hereditary trait corresponds to a specific gene or set of genes that encode the information for that trait. Genes are segments of DNA that determine specific characteristics, such as eye color or height. These genes are inherited from our parents and are responsible for the variation we see in physical attributes and other traits among individuals.
since GENETIC is the compilation of DNA strands to form a gene that acts as a determinant to the growth pattern of an organism, that is the type of hereditary information the organism posses. and VARIATION is a change that exist between organisms..... thus; the word genetic variation is a change that exist between organisms of a particular specie as a result of change(s) that has occurred in their gene....

Sexual reproduction causes variation in organisms because it involves the mixing of genetic material from two parents, resulting in offspring with a unique combination of genes. This variation is essential for the adaptation and evolution of species over time.
The differences shown by the individuals of one kind of organisms are called variations. Variations are due to hereditary and non-hereditary characteristics. Characteristics, which are passed from parents to off spring, are called hereditary characteristics. In general the term variation means the difference in characteristics of organisms belonging to the same species in a natural population. Two types of variation, i.e. continuous and discontinuous, occur in any large population. In continuous variation, there are small differences among individuals of the same species and many intermediate forms are seen. So there is a complete gradation of many characteristics of organisms from one extreme to the other in a population. E.g. height in human being. Characteristics showing continuous variation are produced due to combined effects of many genes and environmental factors.
This pertains to genetics, the branch of biology that studies heredity and variation in living organisms. Genetics involves the study of genes, DNA, and inheritance patterns that determine traits passed from parents to offspring. Genes carry hereditary information that governs the development and functioning of organisms.
Basic source of variation in all organisms is mutation .
an allele is a gene that is the cause of hereditary variation
Variation is important among organisms for us to indicate which is which :))

Meiosis is responsible for genetic variation
Galapagos Islands are the islands where Charles Darwin observed variation among organisms.
Human recombination is a significant source of genetic variation.
VARIATION
Variations arise due to recombinations(gene rearrangements) ,mutations etc.The former is the principal source of variation in sexually reproducing organisms and the latter is the source of variation in asexual organisms.According to Darwin variation arises due to chance since all the above mentioned process occur in nature spontanuously all organisms show variation
