Hereditary variation is best described as

Hereditary variation is best described as characters transmitted from generation to generation. Heredity refers to the passing on of traits or characteristics from parents to their offspring through genetic material (DNA). Hereditary variation refers to the differences in traits or characteristics that exist between individuals of the same species, and which are caused by variations in their genes. These variations may be due to mutations, which are changes in the DNA sequence, or recombination, which is the shuffling of genes that occurs during sexual reproduction. Hereditary variation is important because it provides the raw material for natural selection, which is the process by which organisms with advantageous traits are more likely to survive and reproduce. Therefore, hereditary variation is a key factor in the evolution of species over time.
