Activities to Teach Students to Read a Plant Pedigree Chart

Plant pedigree charts are an excellent tool that is used to study and understand a plant’s genetic traits. These charts depict how different traits have been passed down from previous generations to the current one. However, interpreting a plant pedigree chart can be challenging, and students may struggle to read and interpret them correctly.

To help students understand how to read a plant pedigree chart, here are some activities that teachers can use in their classrooms.

1. Pedigree Chart Poster Activity

This activity focuses on creating a poster that shows the structure of a plant pedigree chart. Students should work in groups to design an appealing poster that demonstrates the structure of a pedigree chart. They can use drawings, diagrams, and other visual aids to make the poster more appealing.

To keep things simple, students can start with a basic pedigree chart and then add more complex traits to it as they progress through the activity. Once they have completed the poster, they can present it to the rest of the class, explaining each part and how they relate to each other.

2. Reading and Analyzing Pedigree Charts

This activity requires students to practice reading and analyzing plant pedigree charts. The teacher can provide several charts for students to work on, and they should identify the tree’s traits that have been passed down from generation to generation.

Students should work in pairs or groups and compare and contrast the various charts, identifying common patterns and genetic traits. This will help them understand how certain genes and traits are inherited from one generation to the next.

3. Identifying Genetic Disorders

This activity focuses on identifying genetic disorders in plants and how they appear on a pedigree chart. The teacher can provide students with a list of genetic disorders and ask them to locate and analyze these disorders on a plant pedigree chart.

Students should pay attention to the pattern of inheritance of the disorders, whether it is an autosomal recessive, autosomal dominant, or X-linked recessive disorder. This activity will help students understand how genetic variants impact plant traits and the challenges that can arise from these mutations.

4. Cross Breeding Exercise

This activity involves cross-breeding plants to create new combinations. A pedigree chart can be used to document the trait inheritance of these new plants. Students should work in groups to choose two different types of plants and document how the traits are inherited in the offspring.

Students can also experiment with different combinations of plants and then document the inheritance of the traits in their offspring. This will help them understand how genes are transmitted from one generation to the next and how genetic traits can be modified through breeding.


Plant pedigree charts are an important tool for studying genetic traits in plants. By using these activities, students can learn how to read and interpret pedigree charts effectively. These activities will help build confidence in their ability to analyze and interpret pedigrees, which will benefit them in the long run. Teachers can adjust the level of difficulty to match the skill levels of their students, making it an engaging activity for everyone involved.
