The study of behavioral genetics holds great promise for revealing the genetic and environmental
factors that impact both typical and abnormal behavior. The ideas and techniques that have been
used to identifying the constituent parts of complex human characteristics serve as the foundation
for behavioral-genetic procedures. To analyze the genetic component of these complex features, new
tools are now accessible. We can start investigating how certain genes interact with environmental
variables in development as they are discovered. Important factors to take into account include how
we interpret these results, how we pose fresh questions, how we celebrate the information, and how
we make use of or abuse this knowledge. These problems are prevalent in all human research fields,
but they are particularly evident in human behavioral genetics. In this article, we review the results of
studies and theories, explore their implications for our knowledge of adult personality development,
and highlight outstanding issues that require more investigation.
