MS-LS3 Heredity: Inheritance and Variation of Traits
| MS-LS3-1. | Develop and use a model to describe why structural changes to genes (mutations) located on chromosomes may affect proteins and may result in harmful, beneficial, or neutral effects to the structure and function of the organism.[Clarification Statement: Emphasis is on conceptual understanding that changes in genetic material may result in making different proteins.] [Assessment Boundary: Assessment does not include specific changes at the molecular level, mechanisms for protein synthesis, or specific types of mutations.]
Unit(s) Task(s) Assessment(s) |
|---|---|
| MS-LS3-2. | Develop and use a model to describe why asexual reproduction results in offspring with identical genetic information and sexual reproduction results in offspring with genetic variation. [Clarification Statement: Emphasis is on using models such as Punnett squares, diagrams, and simulations to describe the cause and effect relationship of gene transmission from parent(s) to offspring and resulting genetic variation.]
Unit(s) Why do different sea stars reproduce differently? Why do Lucy and Maria who are twins look so different? Task(s) Assessment(s) |
