  • 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.

  • Virtual FlyLab (New!)

    Virtual FlyLab (New!)

    Virtual fruit fly genetics lab where students can explore phenotypes and genotypes of flies, design experiments, and perform chi square analysis

  • Genetics Practice (Remote)

    Genetics Practice (Remote)

    This worksheet was modified from a popular (and long-standing) worksheet where students practice genetics crosses: Simple Genetics Practice Problems. This version was created for remote learning during the 2020 pandemic. It is similar to the printout students would normally use, but in the case, I used inserted tables in Google docs to set up the…

  • Genetics – Lop Ears

    Genetics – Lop Ears

    This worksheet allows students to practice doing genetic crosses that involve two traits. The first problem has the 4×4 Punnet square already set up. Once they fill out the square, they determine how many of the bunnies have floppy or long ears, and how many have black or pink noses. Note, these genetic traits are…

  • Practice Problems:  Genetics and Blood Types

    Practice Problems: Genetics and Blood Types

    This worksheet provides students with practice problems on multiple allele traits, specifically on how blood types are inherited.   The problems focus on the ABO blood groups and students are asked to perform crosses where parents’ blood types are known.   For example, if one parent has type O blood and the other parent has…

  • Practice Genetics:  Sex Linked Genes

    Practice Genetics: Sex Linked Genes

    Students learn basic Mendelian genetics by crossing traits from fruit flies and pea plants.  In this extension, students can practice doing crosses that involve sex-linked traits, where the alleles are located on the X chromosome  which affects the pattern of inheritance.   This worksheet is designed for beginning biology students, as it provides in most…
