Mendelian Genetics: Dominant, Recessive, and Punnett Squares - Biology Reading Comprehension Worksheet

Unlock the basics of genetics with this comprehensive reading comprehension worksheet that covers Mendelian genetics, dominant and recessive traits, and how to use Punnett squares to predict inheritance. This resource dives into Gregor Mendel’s groundbreaking experiments, explaining how traits are passed down through generations, and provides a step-by-step guide to understanding dominant and recessive alleles. Students will also practice predicting genetic outcomes using Punnett squares, applying these concepts to real-world examples like eye color inheritance.

What’s Included:

• A detailed reading passage (~1,200 words) covering Mendel’s Laws of Segregation and Independent Assortment, dominant vs. recessive alleles, and how Punnett squares predict inheritance.
• A case study on the inheritance of eye color to help students apply their knowledge.
• Engaging questions, including 3 multiple-choice, 4 matching, 3 fill-in-the-blank, and 3 short-answer questions for comprehension and assessment.
• A teacher answer key for easy grading.
• Structured reading maintains focus on text-based learning and critical thinking.

Why This Resource is a Must-Have:
Perfect for reinforcing lessons on genetics and inheritance, this worksheet helps students grasp complex concepts while developing problem-solving and analytical skills. Use it as a tool for deeper learning, sub plans, or homework assignments to prepare students for success in biology. The content aligns with Common Core standards and supports student understanding of essential genetics principles through practical, real-life examples.

Learning Objectives:

• Understand Mendel’s Laws of Inheritance and the role of dominant and recessive alleles.
