This PowerPoint is a total of 17 slides, which cover the very basic idea of Medal's work, punnet squares, recessive and dominant traits. The presentation is a perfect introduction to the concept of genetics for a intermediate level science class. A unique component embedded into the PowerPoint are the add to notes clues to help foster student note taking skills. The sample PDF contains all the information in the PowerPoint, if you what to get a better idea of the presentation. I feel this PowerPoint gives students a good baseline for understanding genetic concepts without overwhelming them.
