Prepare your students for an exciting journey into the world of genetics with our interactive Google Slides lesson, designed to demystify pedigree charts and empower students to confidently recognize and label genotypes. Dive into the intricate web of inherited traits and discover the science behind family trees.

Why Choose Our Pedigree Analysis Lesson?

Real Human Traits: Explore the fascinating world of genetics through the lens of real human traits, captivating your students' imagination and making learning relatable and engaging.

Interactive Learning: Step into the world of pedigree charts through a guided exploration of three types pedigrees, covering simple dominant traits, simple recessive traits, and sex-linked recessive traits. Students are expertly guided to label genotypes with insightful hints and clues, setting the stage for independent mastery.

Confidence Building: Equip your students with the essential tools to tackle pedigree chart analysis with confidence. Watch as they transform into genetic detectives, unraveling the mysteries hidden within family histories.

Predictive Skills: Witness the evolution of your students' skills as they learn to make predictions from pedigree charts once genotypes are assigned. It's a pivotal step in their genetic journey, fostering a deeper understanding of inheritance patterns.

Practice Makes Perfect: Reinforce learning with three comprehensive practice problems, where students independently assign genotypes and make predictions. Each problem is a new opportunity to solidify their genetic expertise.

Grade & Course Recommendation:

• Middle School: Grade 8 Advanced Life Science, introduction to genetic reasoning.

• High School: Grades 9–10 Biology, genetics and heredity problem-solving unit.

Cross-Curricular Connections (Optional)

• Math Integration: Students apply probability and percentage calculations to inheritance scenarios, reinforcing concepts of ratio and likelihood.

• ELA Integration: The explanation and prediction tasks promote scientific writing and clear communication of reasoning.

• Social Studies Integration: Pedigree studies can connect to historical examples of genetic inheritance in royal families or medical genetics.

Extension Idea:
Have students research a real-world genetic disorder and create a simplified pedigree illustrating its inheritance pattern.

NGSS (Next Generation Science Standards)

High School NGSS Alignment

• HS-LS3-1: Ask questions to clarify relationships about the role of DNA and chromosomes in coding the instructions for characteristic traits passed from parents to offspring.
  Connection: Students use genotypes to predict phenotypes and discuss how allele combinations produce inherited traits.

• HS-LS3-2: Make and defend a claim based on evidence that inheritable genetic variations may result from new genetic combinations through meiosis, errors during replication, and/or mutations.
  Connection: Students explore how allele combinations change across generations due to segregation and recombination.

• HS-LS3-3: Apply concepts of statistics and probability to explain the variation and distribution of expressed traits in a population.
  Connection: Students calculate probabilities of inheritance using pedigree charts and Punnett square reasoning.

Science & Engineering Practices:

• Analyzing and interpreting data (pedigree charts, inheritance models)

• Developing and using models (genotype representation)

• Constructing explanations and using mathematical reasoning

Crosscutting Concepts:

• Cause and effect

• Patterns

• Systems and system models

Middle School NGSS Connections (for adaptation)

• MS-LS3-2: Develop and use a model to describe why sexual reproduction results in genetic variation of offspring.
  Connection: Students can trace variation and inheritance across generations.

Common Core Standards

Grades 8–10:

• CCSS.ELA-LITERACY.RST.9-10.2 / RST.6-8.2: Determine central ideas in a scientific text and summarize how traits are passed from parents to offspring.

• CCSS.ELA-LITERACY.RST.9-10.7 / RST.6-8.7: Integrate quantitative data (percentages, ratios) with visual models (pedigrees).

• CCSS.ELA-LITERACY.WHST.9-10.1 / WHST.6-8.1: Write arguments or explanations supported by evidence (using genotype data).

• CCSS.ELA-LITERACY.WHST.9-10.9 / WHST.6-8.9: Draw evidence from models and data to support predictions.
