When examining heredity, mental disorders are almost always ________

  • A. influenced by one particular gene.
  • B. influenced by multiple genes.
  • C. influenced by recessive genes.
  • D. not influenced by genes.
Correct Answer: B

Rationale: When examining heredity, mental disorders are influenced by multiple genes. Mental disorders are complex conditions that typically result from a combination of genetic, environmental, and other factors. While genetics play a significant role in predisposing individuals to mental disorders, it is rare for a single gene to be solely responsible for a mental disorder. Therefore, choice B is correct. Choices A, C, and D are incorrect because mental disorders are not usually influenced by one particular gene, recessive genes specifically, or not influenced by genes at all.
