Dominant and Recessive Traits

Dominant and Recessive Traits

Author: Caitlin Lubbe

By the end of this lesson, students will be able to explain, verbally and in writing, how different genotype combinations of dominant and recessive alleles for the two parent organisms determines the phenotype of their offspring.

In the lesson tutorial, I will be explaining and showing students the difference between dominant and recessive alleles. They will be taking guided Cornell Notes while they watch the video and do a short written processing piece in the form of adding questions and a summary to their notes. They will also bring 2 questions to discuss in class the next day.

In the classroom lesson, students will work collaboratively to explore how different combinations of dominant and recessive alleles from two parent organisms determines the traits present in their offspring. Students will draw traits randomly from an envelope and record this data. They will then use their genetic data to create an image of what their offspring would look like, and write to explain why their offspring has that specific phenotype, based on the dominant and recessive allele combinations (genotypes) of it's parents.

Dominant and Recessive Alleles, Genotypes and Phenotypes

Directions for PowerPoint Viewing

Tonight, you will prepare for tomorrow's discussion and activity regarding dominant and recessive alleles, as well as genotypes and phenotypes by taking Cornell Notes and completing the appropriate processing pieces...

  1. As you move through the slides of the PowerPoint, fill in the blanks on your Cornell Note Template with the appropriate information.
  2. After you finish the notes, review and edit them by circling, chunking, underlining, and adding question marks to things you still don't fully understand.
  3. Then, go back and add 4 study questions as well as your summary of the notes in the appropriate spaces on your Cornell Note Template. 
  4. Finally, write a question you have that you would like to discuss tomorrow in class.


Have a great night!
