D)a single gene is associated with multiple mental disorders.

Question

Quizplus · Accepted Answer

A polygenic effect refers to the contribution of multiple genes to the development of a mental disorder. It is not caused by a single gene or allele variation, but rather by the complex interplay between a variety of genetic factors. This can make identifying specific genes or genetic markers associated with mental disorders challenging, as it often involves the analysis of large sets of genetic data.
