Heredity: Inheritance and Variation of Traits

Performance Expectations

LS3 help students formulate an answer to the question, “How do living organism s pass traits from one generation to the next?”

The LS3 Disciplinary Core Idea includes two sub-ideas: Inheritance of Traits and Variation of Traits. Students can use models to describe ways gene mutations and sexual reproduction contribute to genetic variation. Crosscutting concepts of cause and effect and structure and function provide students with a deeper understanding of how gene structure determines differences in the functioning of organisms.
