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 significant understanding of how genes impact brain chemistry.

Question

Quizplus · Accepted Answer

Most behaviors are determined by the interaction of many genes and the environment, which makes it difficult to isolate and fully understand the genetic influences on behavior. This is known as the nature vs. nurture debate. While twin studies can provide insight into the heritability of certain traits, they also have limitations and cannot fully separate genetic and environmental effects. Our understanding of how genes impact brain chemistry is still limited and evolving, so D is an incorrect option. A is also incorrect as it is not easy to differentiate between genetic and environmental effects on behavior, which is why this is an ongoing area of research.
