In a world of DNA testing popularity, understanding how to solve basic genetic problems allows scholars to better understand and interpret test results. They work through many different types of genetic problems using statistics, Punnett squares, and probability. After solving each, the next slide offers the correct answer to encourage self-checking.

Instructional Ideas

• Review the difference between genotypes and phenotypes before using the presentation
• Create additional practice problems where pupils know the child's and one parent's genotype and must determine the other parent's possible genotypes

Classroom Considerations

• Relies on prior knowledge of genetics, mutations, algebra, and Punnett Squares

Pros

• Uses high contrast colors for ease of visibility
• Includes the required equations as necessary

Cons

• Slides 36, 41, and 42 all include typos or formatting issues
