Question:

Why do genetic studies provide deep information about living beings? [Pg. No. 247]

Answer: Verified

Genetic studies provide deep information about living beings because genes contain the instructions that control body structure, functions and inherited characteristics. By comparing DNA or genes of different organisms, scientists can find how closely they are related and whether they may have evolved from a common ancestor. Organisms with more similar genetic material are usually more closely related. Thus, genetic studies help us understand classification, heredity, evolution and the diversity of life more accurately than external features alone.
