Investigating Inherited Traits
Objectives:
Students will:
1. Identify dominant and recessive traits
2. Differentiate between homozygous and heterozygous traits
3. Simulate the inheritance of human traits
Materials:
Lab sheets
Quarters
Pencils
Assignments:
Students must work with a partner. Partners will flip coins to complete
the simulation of human inheritance. Once traits are determined, students
will draw the person they created.
Assessment:
Students will earn points for participation and completion of their lab
sheets. Additionally, students will be quizzed at the end of the unit.

Genetics
Objectives:
Students will:
1. Define genetics and heredity
2. Identify dominant and recessive traits
3. Differentiate between homozygous dominant, homozygous
recessive and heterozygous
4. Predict offspring from genetic crosses
5. Explain Gregor Mendel’s importance to the study of heredity
Materials:
PowerPoint slide show
Interactive notebooks
Textbooks
Pens/Pencils
Concept of definition map
Assignment:
Students will answer their IN questions first. Next, students will take
Cornell style notes on Mendel and heredity. Students will then complete
their OUT questions. Finally, each participant will fill out a concept of
definition map about heredity.
Assessment:
Students earn credit for note completion, and will be quizzed at the
end of the unit.

Punnett Squares: Monohybrid Cross
Objectives:
Students will:
1. Identify dominant and recessive traits
2. Differentiate between genotype and phenotype
3. Explain how genotype determines phenotype
4. Describe the process through which traits are inherited
5. Predict offspring using a Punnett square
Materials:
PowerPoint slideshow
Interactive notebooks
White board
Pens
Assignment:
Students will be introduced to Punnett squares. Through the gradual
release method, students will be able to independently complete a Punnett
square to predict the offspring of parents with given traits. Additionally,
students will determine the genotypes and phenotypes of the offspring. At
this time, students will be simply crossing one trait at a time (monohybrid
cross).
Assessment:
Punnett squares will be a component of the unit quiz.
