A consumer asked a genetic scientist whether genes from a genetically modified food plant could possibly cause harm by incorporating themselves into human DNA. What was the scientist’s most likely response? (SC.912.L.16.10)

No, because a person’s genome comes only from the sex cells of parents.
No, because genetically modified DNA can never be passed to offspring.
Too little is known about genetic engineering to be able to answer that question.
No, because humans have always consumed plant and animal DNA with no ill effects.

The scientist’s most likely response would be: No, because a person’s genome comes only from the sex cells of parents.

This response emphasizes that the genetic material that makes up an individual's DNA is inherited from the parents' reproductive cells (sperm and egg), and the DNA from consumed food, even if genetically modified, does not integrate into the human genome.
