However, they are also more likely to grow up in an environment that is conducive to alcohol addiction. Researches have shown the many influence of the environment to the genetic traits. For instance, hormones can trigger the transcription and the translation of the DNA resulting to a specific king of trait and it is a fact that hormone production is partially due to its response to the environment.
