Mendelian Genetics & Inheritance Phenomena-Based Lesson: The Mystery of the Yellow Puppy: Two-Locus Epistasis in Labrador Retrievers Presentation | Biology II | Grades 9–12

This is the student-facing slide presentation that introduces the phenomenon, walks the class through observations and driving questions, and frames the evidence students will use for the Phenomena-Based Lesson in the Biology II (grades 9–12) chapter Mendelian Genetics & Inheritance, built around the phenomenon The Mystery of the Yellow Puppy: Two-Locus Epistasis in Labrador Retrievers. It is sold separately from the other two parts of the set.
