DNA, or Deoxyribonucleic acid, is the genetic code that determines traits in organisms. Variations in this code, called mutations, lead to unique traits. Gene flow, the mixing of genetic information, maintains consistency within a species. When gene flow is restricted, species can diverge, leading to new species. This process, called speciation, contributes to biodiversity.
