The genetic influences that determine behavior may never be fully understood due to
A) the ease of research to differentiate between the effects of the environment and the effects of genes.
B) the likelihood that most behaviors are determined by the interaction of many genes and the environment.
C) the tendency to rely upon twin studies in genetic research.
D) our limited understanding of how genes impact brain chemistry.

Question

Quizplus · Accepted Answer

Most behaviors are determined by the interaction of many genes and the environment, making it difficult to isolate specific genetic influences. While twin studies are commonly used in genetic research, they are not the only method and do not fully account for the complexity of genetic influences. Additionally, while our understanding of the impact of genes on brain chemistry is limited, this is not the primary reason why genetic influences on behavior may never be fully understood.
