AP Bio Ch 13 Human Genetics Quiz
Human genetics as we have come to know is the scientific study of inherited human variation. One benefit of studying is the discovery and description of the genetic contribution to many human diseases. Test out what you know about the genetics of the most interesting species on earth from chapter 13 through this quiz.
