This website explains what the PTC gene is and why some people taste bitter flavors. It explains what the PTC gene is useful for in nature and how natural selection works. It also stated that PTC gene carriers were less likely to be smokers. I choose this resource to go in to depth more about why some people are carriers of this gene and other people are not. It helps explain why it is important in nature, which I thought was cool. I would use this website as tool for myself after giving my students the paper to test for this trait. Then I would explain the benefits of having this gene.

This activity allows students to work with genetics that effect human and animal traits. They will use the worksheets to determine which genes will pass on traits to offspring. Punnett squares are used in the activity to aid the students in finding the answers and understanding the difference between recessive and dominant genes. Students can easily work in groups to complete the science activity and use reasoning techniques to understand how their answers are formed. Along with learning about inheritance and genetics, the students will also be working with probability. This lesson can double as a science and mathematics lesson.

This website is an interactive too for my students to learn about genetics. In this simulation students are given an alien and based on what side the coin lands on in the experiment, and then a particular trait is given. I selected this resource because students might find it engaging, while learning how genetics determines what traits people are given. I might use this activity after I would teach a lesson about recessive and dominant genes, but before I teach Punnett Squares.
