From site:  Meet the Melonheads!  This happy family needs help figuring out which genes they will pass on to their child Melvin.

These genes will decide Melvin’s traits like hair colour, or whether he has dimples.  Can you help them?

From site:  Scitable currently concentrates on genetics, the study of evolution, variation, and the rich complexity of living organisms. As you cultivate your understanding of modern genetics on Scitable, you will explore not only what we know about genetics and the ways it impacts our society, but also the data and evidence that supports our knowledge.

Read more than 150 free, evidence-based articles that explain the science of genetics for undergraduate-level students.

From site:  The Immune System Defender educational game, with three related readings, are based on the 1908 Nobel Prize in Physiology or Medicine, which was awarded for key discoveries about the immune defense system – for identifying certain body cells that engulfe bacteria and for work on trying to explain how antibodies are formed in the body.

In this game, you are a trainee soldier of the Immune System Defense Forces, defending a human against bacterial infection. You have two missions to complete. In the first, you must command a team of white blood cells called granulocytes to fight against bacteria invading the blood system through a finger wound. In the second mission, you must command an army of macrophages and dendritic cells to fight the invading bacteria.

From site: The Control of the Cell Cycle educational game is based on the 2001 Nobel Prize in Physiology or Medicine, which was awarded for discoveries concerning the control of the cell cycle.

– What happens during ordinary cell division – mitosis?
– What happens when a cell dies inside our body?
– How does the body know when to make new cells?
– What are the different phases in mitosis?
– In what order does cell division occur and what ensures that nothing wrong happens?
– How can a cancer tumour be formed?

The cell cycle is the series of events that take place as the cells grow and divide. In average this process takes about 24 hours for cells in mammals. The game is rather easy to go through if you are familiar with the different phases in the cell cycle (cell growth, chromosome duplication, cell growth again, chromosome separation and finally cell division). If you’re not, pay extra attention to the image of the cell cycle in the introduction. As a “Cell division supervisor”, inside the cell nucleus, you are to steer the cell division process to make sure everything happens in the right order. If not, the cell will be destroyed and you’ll have to start all over again. You also have to make controls now and then, to make sure nothing happened with the genetic material on the way. If you make too many mistakes, the energy level in the cell will drop and the cell division will not be able to proceed. The challenge is to complete the game and to make sure that the cell was correctly divided!

Note: This game required Flash to run.

HHMI has an award-winning series of virtual labs, animations and interactive tutorials on dozens of biology topics — from DNA and immunology to infectious diseases and cardiology.  In the Classroom section, there are lesson plans for teachers that accompany many of the topics.  And in Ask a Scientist, there are links to other resources to help answer students questions and help with homework.
