genealogy

From NOVA, this is an online game that lets you introduce mutations to the genetic code of a bug, and see the results.  The game highlights why different cells express different genes, and how different mutations affect gene expression differently.  Includes background information, a lesson plan (under teacher resources) and a student worksheet (under student resources).  Be aware that an audio recording of an article titled "sexual canibilism" (about spiders) is highlighted in the sidebar of this page.
