This packet is everything a parent or guide needs to assess Unit 04 at home — learning targets, the answers that count as correct, the mastery rubric, calibration examples, and a clipboard score sheet. No multiple-choice test: the student shows mastery through trait surveys and Punnett squares, explaining where traits come from.
By the end of the Genetics & Heredity unit, a student should be able to:
Six criteria, each judged Not yet / Approaching / Mastered (Page 3).
Collect trait data and predict offspring outcomes.
The student explains where a trait comes from aloud (Page 4).
Trait data, Punnett squares, and predictions kept distinct.
You are making a decision, not adding up points. For each criterion, decide whether the work is Not yet, Approaching, or Mastered — the column language tells you which. A criterion counts as mastered only when the student can both make the prediction and explain the genetics behind it. A student carries three tokens per term; one token buys a re-do of one criterion on another day, so a single bad afternoon never sinks the unit.
Accept any answer in the synonyms column — they are pre-approved as equivalent. The third column flags the confusions that look close but are not yet, so you can coach precisely.
| Canonical answer | Accepted synonyms | Common confusion / discriminator |
|---|---|---|
| Traits, genes & DNA | ||
| Trait | feature; characteristic | Something about you, like eye color; not always inherited |
| Gene | instruction for a trait | A set of directions, carried by DNA |
| DNA | the code of life | Holds the genes; passed from parents to offspring |
| Heredity | inheritance | How traits pass from parents to their offspring |
| Dominant, recessive & prediction | ||
| Inherited trait | passed from parents | Comes from genes, like eye color — not learned |
| Learned trait | skill; behavior | Picked up by practice, like riding a bike — not passed on |
| Dominant & recessive | stronger vs. hidden | A dominant trait can hide a recessive one |
| Punnett square | prediction grid | Predicts the chances for offspring; not a guarantee |
| Criterion | Not yet | Approaching | Mastered |
|---|---|---|---|
| Traits, genes & DNA | Thinks traits appear at random with no cause. | Says genes carry traits but can’t explain DNA’s role. | Explains that genes are instructions carried by DNA and passed from parents to offspring. |
| Inherited vs. learned traits | Calls every trait, even a skill, something you’re born with. | Sorts most traits but is stumped by tricky ones. | Sorts inherited traits from learned ones and explains why only genes are passed on. |
| Dominant & recessive traits | Doesn’t know that some traits can hide others. | Uses the words dominant and recessive but mixes them up. | Explains how a dominant trait can mask a recessive one and reads a simple genotype. |
| Punnett squares & prediction | Can’t set up a Punnett square. | Fills in a square but misreads the results. | Sets up a one-trait Punnett square and predicts the chances for the offspring. |
| Lab technique (trait survey & Punnett squares) | Collects trait data carelessly or skips recording it. | Gathers trait data but can’t connect it to a prediction. | Runs a clean trait survey, records the results, and uses a Punnett square to explain the pattern. |
| Integration (cross-domain) | Treats the science as isolated facts; makes no cross-domain connection. | Names a link to history, reading, or writing but cannot defend why it matters. | Connects the unit to its anchor across History · Reading · Writing (plus chosen electives) and defends why the connection matters. |
The split between Approaching and Mastered is evidence behind the prediction: not just filling the grid, but explaining why the trait shows up. Ask the student “so where did that trait come from?”
Read these before you grade. They show what Mastered and Not yet actually sound like, plus the edge cases where you should coach rather than decide on the spot.

NY = Not yet · Appr = Approaching · Mast = Mastered · Unsure between two levels? Circle the lower one and note what a re-do would need.
