The concept of shared environment has been of great importance in tackling issues concerning human crime. Hollin (2002) has defined shared environment as environmental factors that are responsible for resemblance or similarity between family members. Shared environment is also defined as family resemblance that is not explained by genetics. Based on these definitions, it is explicit that the concept of shared environment if of great importance in the genetic study of crime, whereby the factors contributing or influencing behavior are analyzed. According to Hollin (2002, environmental influence plays a significant role in determining the nature of human behavior. This does not obstruct the genetic influences but rather tries to establish a strong relationship between the two scenarios.
