Raven Chapter 13 Guided Notes: Patterns of Inheritance
In this short space, it would be impossible to describe the breadth of this seven-page genetics worksheet. Geared toward AP or college biology learners, they explore not only the basic vocabulary and concepts, but also the Law of...

Inheritance Patterns in Zorks
In this inheritance patterns worksheet, students create a visual of a Zork using chromosome strips to represent alleles from the father and the mother to determine the traits in the offspring. Students translate the genotype to the...

Generations of Traits
In this biology worksheet, students track and record the passage of colored pom pom traits through three generations of ginger-bread people. Then they describe that traits are passed from parents to offspring and that siblings may or may...
Curated OER
Genetics Basics
In this basics of genetics worksheet, students review the concepts of genetic inheritance by writing the alleles for genetic traits inherited in offspring. They identify dominant and recessive traits given allele pairs, answer five...

AP: Chapter 14: Mendel and the Gene Idea
A survey of Mendelian genetics is presented through this handout. Biology prodigies answer questions about the Law of Segregation, phenotypic ratios, and dominance. They define genetics vocabulary terms and describe various genetic...

Heredity
In this heredity worksheet, students review how genes are involved in the inheritance of certain traits through generations. Students complete a Punnett square and review probability. This worksheet has 11 short answer and 11 fill in the...
Curated OER
Zork Genetics
In this genetics worksheet, students use an imaginary species and a list of genetic traits and the alleles that code for each trait to determine the genotype and phenotype probabilities of offspring. Students complete nine monohybrid...
