Genetics Quiz: Trivia Test Questions!

Genetics quiz: trivia test questions! The traits of the parents are often passed down to the offspring. A study of genetics has been used to check the likely hood of a person getting a disease from that affected parents. Most people believe that DNA tests how smart someone is, and this quiz is an excellent way to help you learn more about genes. Be sure to give it a shot!
