What is the relationship between DNA and inheritance?

• A. DNA is inherited only in some species.
• B. DNA is not passed to offspring.
• C. DNA is the molecule that allows for inheritance from parent to offspring.
• D. DNA prevents inheritance.

Answer: (C)

DNA carries the instructions for an organism’s traits and is passed from parents to offspring during reproduction, so heredity comes from the genetic material itself. The genes encoded in DNA provide the blueprint that offspring receive, which is why they resemble their parents. As organisms reproduce, DNA is copied and transmitted through gametes, allowing traits to be inherited across generations. Variation in offspring arises from combining parental DNA and from occasional mutations, but the basic mechanism of inheritance is that DNA is the molecule that carries and passes on genetic information. The other statements misstate this relationship by suggesting DNA isn’t transmitted or that it blocks inheritance.
