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

Simulations and Hands-on Activities
Penny Genetics – flip a coin to compare actual outcomes versus predicted outcomes from a Punnett square
Heredity Simulation – use popsicle sticks to show how alleles are inherited
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, Multiple Alleles, and Sex-Linkage
Codominance and Incomplete Dominance – practice genetics on roan cows and pink flowers
Cow Genetics – roan coloration and horns, also includes a two-trait cross
Fruit Flies and X-Linked Traits – practice crosses that involve sex-linkage; fruit flies and calico cats
Sex Linked Traits – students practice doing crosses; tortoiseshell cats, colorblindness, and eye color in fruitflies
Drosophila (Fruit fly) Simulation – use a simulator to run crosses with flies to determine phenotype ratios and perform chi square analysis
Why Are There No Male Calico Cats – case study and slide presentation that explore X inactivation and coat color in cats
