Understand why most real human traits aren’t just “on or off” with this realistic science worksheet on Polygenic Traits and Multifactorial Inheritance!

Perfect for Grades 5–8, this resource explains traits controlled by multiple genes (skin color, height, eye color) plus environmental influence ,  through clear explanations, bell-curve distribution real-world examples, and hands-on activities that graph polygenic outcomes.

Students will see the complexity of inheritance while applying their knowledge through comprehension questions, critical thinking prompts, and interactive practice tasks that build both literacy and science skills.
