D. What is the order of DNA on the genes?

Explanation: Genetic variation arises from differences in DNA sequence (the order of nucleotide bases) between alleles inherited from each parent. Different sequences can change gene products and traits. The other choices (size, shape, or gene count) do not directly explain how different heritable traits arise.
