What characterizes multifactorial diseases compared to single-gene disorders?
What characterizes multifactorial diseases compared to single-gene disorders?
- They result from a combination of multiple genetic and environmental factors. (correct)
- They are exclusively linked to a single genetic mutation.
- They are always caused by environmental factors alone.
- They can only be inherited through dominant alleles.

Study Notes
Genetic Disease Development
- Many genetic diseases aren't caused by a single gene, but by multiple factors working together.
- Multifactorial diseases are influenced by both genetic and environmental factors.
- A predisposition to the disease (genetic factor) and environmental factors combine to cause the disease.
