  • 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 Practice Problems with Google Slides

    Genetics Practice Problems with Google Slides

    For students who are learning remotely, genetics lessons that involve Punnett squares and probability may be challenging.  In a traditional class, I would give students small whiteboards and we would practice doing crosses together. I could circulate around the room to help students who are struggling, and they could help each other. Plus, they love writing…

  • Population Genetics in a Fishbowl

    Population Genetics in a Fishbowl

    Students learn about Hardy-Weinberg equilibrium by exploring a virtual population of koi fish. This virtual lab allows students to run experiments where they can change variables, like population size, migration rate, mutation rate, and fitness of two separate alleles. The alleles being studied control the coloration of the fish. Fish can either be white, gold,…

  • Speciation Modes on

    Speciation Modes on

    This activity was designed for students during the COVID-19 pandemic and is intended to be completed individually at home. The lesson explores the two models of speciation: allopatric and sympatric. You can also assign a simple print version that explores speciation modes. Students first read about allopatric speciation and apply it to the finches on…

  • Bear, Species, & DNA

    Bear, Species, & DNA

    This activity was created during the Covid-19 pandemic for students to complete at home using the interactive explore at Learn.Genetics. The activity is probably best for 2nd year biology students or AP Biology, but it could potentially work with first year students. The questions aren’t hard, but the concepts can be difficult to grasp. 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…

  • Dog Tales – NOVA

    Dog Tales – NOVA

    Worksheet for the NOVA program “Dog Tales” which explores the evolution and domestication of dogs. Includes multiple choice questions with a final reflection.

  • 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.

  • Horse Genetics

    Horse Genetics

    Practice genetic crosses with horse traits. The gait-keeper gene controls whether a horse will trot or pace and the flaxen gene determines mane color.

  • Genetic Crosses – 2 Traits

    Genetic Crosses – 2 Traits

    This worksheet was designed for freshman learning dihybrid crosses. Students struggle with setting up Punnet squares, so the squares are set up for them at first. Students only need to fill in the letters of the genotype can determine the phenotype proportions. A final task requires students to set up their own 4×4 square when…

  • Genetics: Sexy Chickens

    Genetics: Sexy Chickens

    This worksheet was designed for advanced students of biology or for honors students who are ready for an extra challenge. Birds have a ZW sex determination system instead of the XY system seen in humans. If your students have a good grasp on sex-linked traits in humans, then this scenario is a way to really…

  • Genetics of Sickle Cell

    Genetics of Sickle Cell

    This assignment was created for students who miss class and can be completed independently. There are sections to read with questions to answer, focusing on how DNA provides the instructions to make protein. A single base substitution in the gene that codes for hemoglobin results in sickle cell anemia. Students are walked through the process…

  • Genetics of Chicken Combs

    Genetics of Chicken Combs

    The combs of chickens are controlled by four alleles, which interact to produce four distinct phenotypes: single, rose, pea, and walnut. In this exercise, students predict the outcomes of chicken crosses. Ideally, students should already know how to do crosses that involve two traits, the mechanisms for solving these problems are similar. My honors biology…

  • Pedigrees – Human Genetic Disorders

    Pedigrees – Human Genetic Disorders

    Students practice identifying genotypes on pedigree charts. Focus on human genetic diseases, such as albinism, dwarfism, tay-sachs, and sickle cell anemia.

  • Genetics Practice Problems – Easy Mode

    Genetics Practice Problems – Easy Mode

    This worksheet was created for an introductory level biology class. This worksheet is designed to move through difficulty levels, so students start with “easy mode,” then moving to “normal” and then finally “hard mode.” Students can move at their own pace, which instructors can help students who are struggling.
