Help your students build a strong foundation in heredity and genetics with this comprehensive Genetics Bundle, featuring two engaging, no-prep resources designed for middle school science! This bundle includes everything you need to teach both Mendelian genetics through Punnett Squares and non-Mendelian inheritance through incomplete and complete dominance.

Students will explore how traits are passed down, analyze genotype and phenotype combinations, and practice solving Punnett Squares with clear, student-friendly explanations. Each resource includes reading passages, guided notes, vocabulary reinforcement, real-world examples, and higher-order thinking questions—all aligned with NGSS MS-LS3-1 and MS-LS3-2.

This bundle is perfect for launching your genetics unit, reviewing key concepts, or preparing students for more advanced biology topics. Whether you're using it for classwork, homework, stations, or sub plans, it's print-and-go and digital-ready!

Students Will:

• Understand the difference between dominant, recessive, and incomplete dominance
• Use Punnett Squares to predict genotypes and phenotypes of offspring
• Identify heterozygous and homozygous combinations
• Analyze inheritance patterns in Mendelian and non-Mendelian crosses
• Apply key genetics vocabulary in context
• Practice reading comprehension, logic, and scientific modeling
• Build confidence in solving genetics problems independently

What’s Included:

1. Punnett Squares Resource:

• Reading passage: What Are Punnett Squares?
• Step-by-step instructions for solving monohybrid crosses
• Guided fill-in-the-blank notes
• Vocabulary matching activity
• Practice Punnett Squares with ratio analysis
• Critical-thinking and analysis questions
• Complete answer key

2. Incomplete vs. Complete Dominance Resource:

• Reading passage comparing incomplete and complete dominance
• Practice questions using real-world traits (e.g., flower color, hair type)
• Genotype and phenotype analysis
• Vocabulary practice
• Answer key included
  

Perfect For:

• Middle school science classrooms (grades 6–8)
• NGSS-aligned heredity and variation units (MS-LS3-1 & MS-LS3-2)
• Introduction, reinforcement, or review of genetics concepts
• Homework, sub plans, science centers, or independent work
• Supporting visual and reading comprehension learners
  

Make genetics approachable, engaging, and easy to teach with this all-in-one Punnett Square and Dominance bundle—ideal for your middle school science classroom or digital instruction needs!
