Multifactorial disorders involve the interaction of a single gene defect with several environmental factors. True or False?
Understand the Problem
The question is asking whether multifactorial disorders are characterized by the interaction of a single gene defect with multiple environmental factors, which indicates that the answer choices are determining the truth of a statement.
Answer
False. They involve multiple genes and environmental factors.
False. Multifactorial disorders involve the interaction of multiple genes, usually polygenes, and environmental factors, not a single gene defect.
Answer for screen readers
False. Multifactorial disorders involve the interaction of multiple genes, usually polygenes, and environmental factors, not a single gene defect.
More Information
Multifactorial disorders arise from the complex interplay of multiple genetic factors along with environmental influences. These are distinct from single-gene disorders, which are caused by mutations in one gene.
Tips
A common mistake is confusing multifactorial disorders with single-gene disorders. It's important to recognize that multifactorial disorders involve several genetic and environmental elements.
