Genetics of Blood Disorders – Hemophilia and Sickle Cell
I created this worksheet for anatomy students to practice using Punnett squares and comparing different types of mutations that affect the blood. Ideally, students will have already learned about genetics of blood types. Because I use this worksheet in my anatomy class, I don’t spend a lot of time teaching genetics. However, students do need…

Genetic Crosses in Rabbits (Remote)
Students learn how to do Punnett squares with two traits by practicing completing 4×4 squares.

Karyotype Analysis Using Google Slides
Students group homologous pairs of chromosomes and arrange them by size on the grid using google slides. Diagnose the genetic disorder.

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
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…

Investigation: Sticklebacks
This investigation was modified from the HHMI Stickleback Modeling activity where students examine two different forms of the the stickleback fish. One form has spines and bony armor and is found in the ocean. The other has less armor and is missing its pelvic girdle, and is found in fresh water lakes. The activity has…

Case Study: Cystic Fibrosis Mutations
This case study is a follow-up to the Cystic Fibrosis Case Study where students explore how changes in transport proteins affects the movement of ions, resulting in a build-up of chloride ions and the symptoms of the disease. Students were introduced to the idea that different mutations can cause differences in the transport proteins, but…

Label: Protein Synthesis
Label and image of the cell membrane and ribosome, showing transcription and translation.

Amylase Enzyme and Copy Number Variant
This activity explores a data set on the frequency of copy number variants in the gene AMY1 that codes for amylase activity in the saliva. Amylase is an enzyme that breaks down starch into sugar. The activity builds on the HHMI data point showing how presence of multiple copies of the gene correlate to populations…

DNA Drag and Drop
Label DNA models by dragging boxes to the correct spot on Google Slides. Models show major events in DNA replication, and molecules involved.

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…

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
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
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…

Reinforcement: Genetics
This exercise was created for an intro bio class though it would also be appropriate for other levels or students who struggle with basic vocabulary. The word list includes terms such as: phenotype, genotype, heterozygous, dominant, and recessive. Also included on the list are several genetic disorders like hemophilia and sickle cell. The worksheet was…
