    Case Study – The Island of the Colorblind

    Looking for a high-impact, real-world genetics case study to bring recessive inheritance and population genetics to life? Let me introduce you to Pingelap Atoll, a remote island in Micronesia with a powerful story that blends biology, history, and human resilience. 🧬 What’s the Story? Pingelap is known as “The Island of the Colorblind”, thanks to…

  • The Genetics of Frizzle Frazzle Chicks

    The Genetics of Frizzle Frazzle Chicks

    Frizzle feathers in chickens is the result of a dominant allele. Practice crosses between different types of chickens, by completing Punnett squares.

  • Peas, Please! – A Practice Set on Mendelian Genetics

    Peas, Please! – A Practice Set on Mendelian Genetics

    Students practice assigning genotypes (PP, Pp, or pp) to different traits based on whether the trait is dominant or recessive. They set up Punnett squares, and determine the phenotypic ratios of the offspring.

  • Pedigree Analysis – AP Bio

    Pedigree Analysis – AP Bio

    Designed for biology students studying genetics. Determine the inheritance pattern for human disorders, like Tay-Sachs or Marfan Syndrome.

  • Investigation:  Modeling Heredity with Popsicle Sticks

    Investigation: Modeling Heredity with Popsicle Sticks

    In this activity, you will use popsicle sticks to model the process of gamete formation and the combining of sperm and egg to create offspring. Results of the simulation can then be compared to Punnet square expected results. Popsicles should be made in advance, the set contains a male and female set with the genotypes…
