Unit Plan Unit Author First and Last Name: Peter Berry School District: Middletown School Name: Middletown High School School City, State: Middletown, CT Unit Overview Unit Plan Title: Fundamentals of Genetics and Inheritance Curriculum-Framing Questions Essential Question Unit Questions How are traits passed from one generation to the next? 1. Why do traits often appear to skip a generation, disappearing in one, and then reappearing. 2. Can you predict what traits offspring will have? 3. What must happen to the genetic material in an organism when sex cells (gametes) are formed? 4. How many types of offspring would result from crossing organisms that were heterozygous for two recessive traits? Unit Summary: This unit will introduce students to the concept of “blending” to explain inheritance and Gregor Mendel’s experiments showing that individual factors (genes) that do not blend control each trait. The concepts of dominant, recessive, co-dominant, and incomplete dominance, alleles of genes, independent assortment, and genotype versus phenotype will be covered.

All Rights Reserved 2 Targeted State Frameworks/Content Standards/Benchmarks: State Standard 6: Cycles of Life: Students will recognize patterns and products of genetics and evolution: Compare and contrast Mendel’s laws (segregation and independent assortment) of heredity. Explain how new heritable characteristics can result from new combinations of genes. Student Objectives/Learning Outcomes: Content: -Compare and contrast dominant, recessive, co-dominant and incomplete dominant traits. -Describe the relationship between genes and alleles. -Describe the experiments of Gegor Mendel. -Evaluate the use of peas for research in inheritance. Process: -Predict the ratios of phenotypes and genotypes in monohybrid and dihybrid crosses. -calculate the probabilities of results of different crosses. -Observe and analyze the results of dominant and recessive crosses in class activity Product: -Produce Punnett squares for F1and F2 generations of dominant and recessive traits. -Produce Punnett squares for F1 and F2 generations of dihybrids. -Develop a pedigree for a dominant/recessive trait. Procedures: Students will study Mendel’s pea experiments, and the resulting inheritance patterns. Students will use Punnett squares to predict the ratios of offspring from various genetic crosses. Students will complete a project to demonstrate their understanding of inheritance patterns.
