HS-LS3 Heredity: Inheritance and Variation of Traits
| 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. [Assessment Boundary: Assessment does not include the phases of meiosis or the biochemical mechanism of specific steps in the process.]
Unit(s) Unbreakable Bones as a Superpower Chicken Cell Differentiation Unit Sickle Cell Anemia/Malaria Unit Task(s) Assessment(s) |
|---|---|
| HS-LS3-2. | Make and defend a claim based on evidence that inheritable genetic variations may result from: (1) new genetic combinations through meiosis, (2) viable errors occurring during replication, and/or (3) mutations caused by environmental factors. [Clarification Statement: Emphasis is on using data to support arguments for the way variation occurs.] [Assessment Boundary: Assessment does not include the phases of meiosis or the biochemical mechanism of specific steps in the process.]
Unit(s) Unbreakable Bones as a Superpower Why do Lucy and Maria who are twins look so different? Task(s) Assessment(s) |
| HS-LS3-3. | Apply concepts of statistics and probability to explain the variation and distribution of expressed traits in a population.[Clarification Statement: Emphasis is on the use of mathematics to describe the probability of traits as it relates to genetic and environmental factors in the expression of traits.] [Assessment Boundary: Assessment does not include Hardy-Weinberg calculations.]
