- Traits are frequently influenced by environmental factors rather than genetics. Although not always. Sometimes a gene's DNA sequence or degree of activity is altered by the environment.
- The proteins that a gene produces can be replaced by either of these effects, which in turn impacts characteristics.
- The nucleotide sequence of a gene may alter as a result of some harmful environmental influences. DNA strands, for instance, can be damaged by UV light.
- Certain pollutants, such as those found in plastic and cigarette smoke, can change how DNA bases behave chemically, allowing one DNA base to stand in for another.
