Question 1

Question 2

Applications

Answer 2

An understanding of how our genotype (genetics) interacts with the environment to produce our phenotype helps us to treat things such as depression. We understand that there can be a biological vulnerability (genetics) but this is triggered by the environment. Treatments for depression can therefore focus on both for example drug treatments and stress reduction.

Question 3

Weaknesses

Answer 3

Oversimplification and an incomplete theory because it ignores the importance of other factors. Cognitive factors and learning have been shown to be important in the development of disorders such as depression, it cannot simply be explained by looking at a ‘gene’.
