Question

Quizplus · Accepted Answer

While genes do play a role in determining an organism's traits, the expression of those traits can be influenced by environmental factors. In other words, gene expression can be "turned on" or "turned off" depending on the environment, so the relationship between genes and phenotype is not always straightforward. Option A is not entirely accurate because genes do not always specify phenotypes directly, but rather they contribute to the development of traits in complex ways. Option C is incorrect because the effects of genes and environment are often intertwined and difficult to tease apart. Option D is also incorrect because people's traits are influenced by both their genes and their environment.
