# Heredity: Inheritance and Variation of Traits

### Students who demonstrate understanding can:

#### Performance Expectations

1. Apply concepts of statistics and probability to explain the variation and distribution of expressed traits in a population.

Clarification Statement and Assessment Boundary

A Peformance Expectation (PE) is what a student should be able to do to show mastery of a concept. Some PEs include a Clarification Statement and/or an Assessment Boundary. These can be found by clicking the PE for "More Info." By hovering over a PE, its corresponding pieces from the Science and Engineering Practices, Disciplinary Core Ideas, and Crosscutting Concepts will be highlighted.

### Science and Engineering Practices

By clicking on a specific Science and Engineering Practice, Disciplinary Core Idea, or Crosscutting Concept, you can find out more information on it. By hovering over one you can find its corresponding elements in the PEs.

## Resources & Lesson Plans

• More resources added each week!
A team of teacher curators is working to find, review, and vet online resources that support the standards. Check back often, as NSTA continues to add more targeted resources.
• In this HHMI Biointeractive hands-on activity, students use photos of stickleback fish to analyze the results of genetic crosses between fish with different traits.  Students are introduced to the activity through a suggested video: "Studen ...

•   In this activity, students apply their knowledge of  models  of inheritance (dominant-recessive, co-dominance, incomplete dominance, multiple alleles, and sex-linked) to determine how fruit flies inherit a specific trait. The guid ...

• In this lab activity from the book Argument-Driven Inquiry in Biology, students use an online simulation (www.fastplants.org/legacy/genetics/Introductions/two-trait.htm) to cross Wisconsin Fast Plants with different traits and identify inheritance pa ...

• These are the Slide for "Beyond Earlobes and Tongue Rolling"

• In this activity, students calculate temperatures during a time in the geologic record when rapid warming occurred using a well known method called 'leaf-margin analysis.' Students determine the percentage of the species that have leaves with smooth ...

• In this interactive, students explore, at their own pace, how global climate change may affect health issues. Issues include airborne diseases, developmental disorders, mental health disorders, vector-borne diseases and waterborne diseases.

• In this activity from NOAA's Okeanos Explorer Education Materials Collection, learners investigate how methane hydrates might have been involved with the Cambrian explosion.

• Students use simulations (https://www.biologysimulations.com/heredity) to test is two genes assort independently.

• Students use a heredity simulation (https://www.biologysimulations.com/heredity-ii) to test predictions for an x-linked gene.

• The Natural Selection virtual lab allows students the opportunity to investigate into how natural selection leads to the predominance of certain traits in a population, and the suppression of others. Therefore, through this virtual lab, students will...

• The goal of the Diversity of Traits virtual lab is to allow students the opportunity to investigate how variations of traits can occur because of mutations. This virtual lab complements the Natural Selection virtual lab by addressing a common misconc...
