Inheritance of Coat Color in Labrador Retrievers has been the all time favorite project of my Biology students for over 10 years and I’m sure your students will love it, too!

It’s a real-world scenario about inheritance patterns in one of America’s favorite dog breeds. Students will assume the role of a genetic counselor and use what they’ve learned about patterns of inheritance, Punnett squares, and Mendel’s Law of Independent Assortment to advise two dog breeders who want more chocolate puppies. The concept of epistasis will also be introduced; a topic most students don’t learn until AP Biology.

This download includes 9 files:

1. Read This First includes project overview, terms of use, and image credits.

2. Teacher’s Guide with complete explanation of the project and the solution.

3. Genetics Project Handouts for Students include 3 pages of instructions and information needed to solve the breeder’s problem.

4. Project Task 1 introduces the epistatic pattern of inheritance and provides practice in interpreting and determining genotypes and phenotypes.

5. Answer Key to Project Task 1

6. Project Task 2 presents opportunities for students to draw and analyze Punnett Squares using two gene pairs.

7. Answer Key to Project Task 2

8. Adorable Labrador Retriever Pictures your can print for your students or post in your classroom.

9. Editable Project Rubric for grading student projects.

I usually allow 1 ½ - 2 weeks from the time I introduce this performance task to students until the due date of the project. I like to use the last 15 minutes or so of 3 consecutive classes to introduce the project and give daily tasks to get students started. After that, they can usually run with it and put their presentations together. You can decide if you prefer students to work individually or in groups – it works well either way. I hope you enjoy this project as much as I do!

to see state-specific standards (only available in the US).
Apply concepts of statistics and probability to explain the variation and distribution of expressed traits in a population. Emphasis is on the use of mathematics to describe the probability of traits as it relates to genetic and environmental factors in the expression of traits. Assessment does not include Hardy-Weinberg calculations.
Ask questions to clarify relationships about the role of DNA and chromosomes in coding the instructions for characteristic traits passed from parents to offspring. Assessment does not include the phases of meiosis or the biochemical mechanism of specific steps in the process.
