In modern psychology, people’s personality and behavior can be defined as the interdependence of inheritor factors or inherited traits (nature) and the impact of upbringing and education (nurture).

1. Genetic Predispositions: Genes contain an architectural plan for possibly implying the attributes, such as extroversion or resilience; however, genes do not create the outcome independently.

2. Environmental Influences: It is, therefore, important for people to understand that family, education, and culture play a role in determining how genes are formed. For instance, a well-nurturing environment will genetically endow intelligent people with the ability to express themselves fully.

3. Interaction and Epigenetics: Epigenetics occurs when some experiences lead to changing the genotype or turning it on or off as a result of the environment. Chronic stress or trauma in one’s youth can change how genes are regulated and hence affect behavior.

4. Developmental Perspective: The importance of nature and nurture changes with the age of the child. An individual’s early learning leaves lifelong impressions; however, people’s everyday transactions perpetually influence their personalities and actions.

Thus, it is apparent that the dual processes of genes and environment interaction fix personality and behavior.
