Explanation:
Detailed explanation-1: -The deoxyribonucleic acid (DNA) of closely related organisms would be more similar to each other as compared to distantly related organisms. This is because closely related organisms share a common ancestor and may have similar traits or characteristics. Such organisms also retained lesser mutations over time.
Detailed explanation-2: -Comparing the DNA sequences of different species is a powerful method for decoding genomic information, because functional sequences tend to evolve at a slower rate than nonfunctional sequences.
