1. Why is it flawed to ask how much of a particular behavior is due to genetics and how much is due to experience?
2. Why is it appropriate to separate the contributions of genetics and experience when measuring the development of differences among individuals?
Whether we are studying species, populations, or individuals, the genetic and experiential influences share a bidirectional, complex, interaction. One of the ways to address the issue of nature vs. nurture is to study the field of epigenetics (see figure attached). The concept of the gene x environment interaction is that their bidirectional influence promotes the development of a certain trait or characteristic, as opposed to the view that the processes and factors of nature and nurture are ...
Concepts between pro nature and pro nurture are fully summarized in this solution.
