Genetics Warm Up 1
Welcome to the electronic frontier classroom of the 21st Century. Genetics is the field of biology devoted to the research and understanding how characteristics are transmitted from parents to offspring. Let us see how well you of a basic understanding you have of Gregor Mendel and his garden peas. This warm up allows unlimited number of attempts and randomly generates the order of questions and answer. Good Luck and I wish you well in earning a high grade!
