Furthermore, genetic factors always work with environmental factors to create personality.

The findings suggest that family factors play a critical role in shaping the trajectory of an infant’s behavioral style as it unfolds over development.

The influence of genes on behavior has been well established in the scientific community. To a large extent, who we are and how we behave is a result of our genetic makeup. While genes do not determine behavior, they play a huge role in what we do and why we do it.

What is more influential in determining personality nature or nurture?

Overall, genetics has more influence than parents do on shaping our personality. Molecular genetics is the study of which genes are associated with which personality traits.

Bioindicators include biological processes, species, or communities and are used to assess the quality of the environment and how it changes over time. Bioindicator species effectively indicate the condition of the environment because of their moderate tolerance to environmental variability (Figure 1).
