# SZ3: Morphological and Genetic Traits

Obtain, evaluate, and communicate information to compare and contrast structure and function of morphological and genetic characteristics across representative taxa.

- Subject: Science
- Appears in: High School, https://georgiahomeroom.org/standards/science/high-school.md

## Expectations

- **SZ3.a**: Plan and carry out investigations to determine patterns in morphology (including organ systems, symmetry and body cavities) of representative animal taxa.
- **SZ3.b**: Construct an explanation of life functions (i.e., reproduction, respiration, digestion) at appropriate level of organization for representative taxa.
- **SZ3.c**: Construct an explanation based on evidence to relate important structural changes across evolutionary history to key functional transitions.

## Georgia Milestones coverage

No Georgia Milestones blueprint cites this standard.
