Answer:
No, since DNA does code for certain traits, others are introduced or changed by the environment. For example, some adaptations are not coded in DNA, such as dying hair. According to the gene, hair is to be black, for example, but it can be changed to look pink. Another example is when a person is first born. When they are, some bacteria enter the system of the baby --- mostly good. Then the baby's gut will be different, and the bacteria in the gut are not coded by the DNA. So, living things are not only the product of DNA, as there are extraneous factors that affect living things as well.
