Genetics includes the study of heredity, or how traits are passed from parents to offspring. The topics of genetics vary and are constantly changing as we learn more about the genome and how we are influenced by our genes.
Inheritance Patterns and Punnett Squares
Heredity Simulation – use popsicle sticks to show how alleles are inherited
Penny Genetics – flip a coin to compare actual outcomes versus predicted outcomes from a punnett square
Heredity Wordsearch – fill in the blank, find the words on a puzzle, basic vocabulary
Simple Genetics Practice – using mendelian genetics and Punnett squares
Bunny Genetic Crosses with two traits – basic crosses, uses Punnett squares
Horse Genetics – basic practice worksheet on monohybrid and dihybrid crosses, using a gait trait found in horses
Fruit Fly Genetics (Vg) – practice worksheet on vestigial wing flies (recessive trait)
Genetics Practice Problems – crosses involving guinea pigs, goats, and pea plants; monohybrid and dihybrid crosses
Blood Disorder Genetics – a worksheet with genetics problems that relate to specific disorders: sickle cell anemia, hemophilia, and Von Willebrand disease.
Variations on a Human Face – toss a penny to determine the features of a face, such as freckles, dimples; then draw that face.
Paper Pets – another simulation using paper models with traits for eyes, nose, mouth, and hair.
Codominance and Multiple Alleles
Codominance and Incomplete Dominance – practice genetics on roan cows and pink flowers
Fruit Flies and X-Linked Traits – practice crosses that involve sex-linkage; fruit flies and calico cats
Blood Type Genetics – practice with blood type crosses and other ABO type alleles, multiple allele traits
Multiple Allele Traits in Chickens – shows how combs are inherited (rrpp x RRpp)
How Do Genes Determine Skin Color? – this case study uses presentation slides to explore a real-life scenario where a Nigerian mother has two very fair skinned children.
Why Are There No Male Calico Cats – case study and slide presentation that explore X inactivation and coat color in cats
Design-a-Species – using the rules of inheritance (mendel), create an organism; with dominant and recessive traits, multiple allele traits, and codominance
Genetics and Statistics
Hardy-Weinberg Problem Set – statistical analysis, using HW equation and some dragons
Hardy Weinberg Simulation – track an allele in population by simulating how parents pass alleles to offspring
Corn Genetics and Chi Square – statistical analysis, using preserved corn and counting kernels
Albino Corn Genetics – grow corn, 3:1 albino ratio, lab report analyzes F1, F2 crosses
Chi Square Modeling Using Candy – count the number of each color in a bag to determine if they occur in equal proportions
Drosophila Virtual Lab – choose fruit fly parents and analyze offspring in this virtual lab
Meiosis Label – look at cells in various stages of meiosis, identify and order
How to Interpret a Karyotype – examines images of human karyotypes to identify disorders
Meiosis Internet Lesson – look at animations of meiosis and answer questions
Modeling Chromosomal Inheritance – use pipe cleaners to show how genes are inherited; independent assortment, segregation, sex-linkage
Linkage Group Simulation – uses pipe cleaners and beads, students construct chromosomes with alleles and perform crosses, predicting outcomes (advanced)
Karyotyping Online – use a website simulator to learn how to pair chromosomes and diagnose abnormalities
Chromosome Study – cut out chromosomes and tape them in pairs to construct a “paper” karyotype
SRY not SRY – case study on gender and sex chromosomes
Coloring DNA – basic image of DNA and RNA for students to color following directions; includes questions and analysis
DNA Crossword – puzzle to practice basic terms related to DNA
How Can DNA Replication Be Modeled – students use colored paperclips to model how one side of the DNA serves as a template during replication (semi-conservative)
Drosophila and the Homeobox – explore genetic mutations in fruit flies that are associated with Hox genes
Gene Regulation in Prokaryotes – focuses on the lac operon and how some genes are repressible
Transcription & Translation Coloring – shows structures involved, nucleotides, base pair rules, amino acids
DNA Analysis: Recombination – simulate DNA recombination using paper slips and sequences
Strawberry DNA Extraction – instructions for extracting DNA from a strawberry, very simple, works every time!
How DNA Controls the Workings of a Cell – examine a DNA sequence, transcribe and translate
DNA Sequencing in Bacteria – website simulates the sequencing of bacterial DNA, PCR techniques
Who Ate The Cheese – simulate gel electrophoresis to solve a crime
HIV Coloring – shows how viral DNA enters and infects a cell
Genetic Science Ethics – survey as a group ethical questions involved genetics (cloning, gene therapy..)
Your Genes Your Choices – this is a more involved group assignment where groups read scenarios about genetic testing and ethics involved.
