I wrote about a paper appearing in Science today that compares public acceptance of evolution in the United States versus other countries. As part of the study, the researchers reviewed surveys in which adults were given 10 True or False statements (listed below) to test their understanding of basic concepts from genetics.

Each correct answer was worth one point. The median score for American adults was 4. How do you fare? (**answers at bottom of post)

1. Ordinary tomatoes do not have genes, whereas genetically modified tomatoes do.

2. Genetically modified animals are always larger than ordinary animals.

3. Cloning is a form of reproduction in which offspring result from the union of sperm and egg.

4. Today it is not possible to transfer genes from humans to animals.

5. If someone eats a genetically modified fruit, there is a risk that a person’s genes might be modified too.

6. All plants and animals have DNA.

7. Today it is not possible to transfer genes from animals to plants.

8. Humans have somewhat less than half of the DNA in common with chimpanzees.

9.. It is possible to extract stem cells from human embryos without destroying the embryos.

10. All humans share exactly the same DNA.

**Use your mouse to highlight below to see the answers:

All statements are false except number 6.
