Nice site for research on genetic disorders. When you choose a disorder, you get a short explanation of that disorder. If you want more information, you just click on the menu to the left and the details. Rather interesting, to be honest. I watched the animation on Sickle Cell Anemia and learned quite a bit. Presented very simply, yet with lots of details and a full explanation, not only on the anemia, but on how it all ties in with the genetics and the every day working of the blood cells. I’m sure the other links are just as useful.
