Chapter 6 · DNA, Inheritance & Gene Expression
Assigned readings
Follow the chapter question: How does genetic information contribute to traits without determining every outcome alone?
This week’s goals
- Explain the figures, mechanisms and quantities before calculation.
- Distinguish source observations, illustrative records and hypotheses.
- Apply independently and revise from evidence.
Read From an allele symbol to a measured characteristic at this chapter’s launch, then use its linked unit explanations and source records in the assigned sessions.
Five flexible sessions, normally about 50–60 minutes. Unit study uses three sessions. The sample keeps a complete 90-minute extended sitting paired with about 30 minutes of correction; extend teaching when needed.
Session 1 · Compare Expected and Observed Inheritance — plan and model
How close must a small sample be to a probability prediction?
Your task
Choose the stated safe material or supplied-record route, define variables/controls and draw a prediction.
- Prepare the assigned reading and identify the question.
- Trace the figures and retain a labeled first model or prior attempt.
- Complete the stated task before opening guidance.
- Compare reasoning with criteria, explain a correction and retain the revised evidence.
Hint and response guidance
Name the structures, quantities, system boundary and assumptions before selecting a mechanism.
Expected aa frequency is 25%. Group percentages are 15%, 35%, and 25%; combined, 15 of 60 = 25%. The agreement in the combined table is illustrative, not a rule guaranteeing exact convergence in every larger sample. Eye color involves several genes; this hypothetical cross illustrates probability under specified assumptions. A complete response also states the system boundary, units, matched conditions and limitations. Distinguish supplied illustrative outcomes from collected measurements, and explain why your revised mechanism fits the relevant evidence. Different observations should be interpreted rather than replaced to match the example.
- Use the stated evidence and correct units.
- Explain a biological mechanism or relationship.
- Show intermediate reasoning with a labeled figure or calculation.
- State a limitation and a useful revision/test.
Session 2 · Compare Expected and Observed Inheritance — records and comparison
How close must a small sample be to a probability prediction?
Your task
Use the given method and safety notes; collect or analyze records with units, repeats and honest variation.
- Prepare the assigned reading and identify the question.
- Trace the figures and retain a labeled first model or prior attempt.
- Complete the stated task before opening guidance.
- Compare reasoning with criteria, explain a correction and retain the revised evidence.

Session 3 · Compare Expected and Observed Inheritance — explain and revise
How close must a small sample be to a probability prediction?
Your task
Graph, explain the mechanism, assess a limitation and revise the first model; submit a complete notebook.
- Prepare the assigned reading and identify the question.
- Trace the figures and retain a labeled first model or prior attempt.
- Complete the stated task before opening guidance.
- Compare reasoning with criteria, explain a correction and retain the revised evidence.

Session 4 · DNA, Inheritance & Gene Expression — chapter review
Use the linked unit explanations, figures and the learner’s notebook.
Your task
Attempt the chapter review before opening solutions. Include each unit’s new visual-transfer case and connect mechanisms across the chapter.
- Prepare the assigned reading and identify the question.
- Trace the figures and retain a labeled first model or prior attempt.
- Complete the stated task before opening guidance.
- Compare reasoning with criteria, explain a correction and retain the revised evidence.
Hint and response guidance
Name the structures, quantities, system boundary and assumptions before selecting a mechanism.
Use the review solutions and question-specific rubrics; an equivalent evidence-supported explanation is valid.
- Use the stated evidence and correct units.
- Explain a biological mechanism or relationship.
- Show intermediate reasoning with a labeled figure or calculation.
- State a limitation and a useful revision/test.
Session 5 · DNA, Inheritance & Gene Expression — chapter quiz
Use the linked unit explanations, figures and the learner’s notebook.
Your task
Complete the chapter quiz independently, then use the objective key and human marking criteria for written responses.
- Prepare the assigned reading and identify the question.
- Trace the figures and retain a labeled first model or prior attempt.
- Complete the stated task before opening guidance.
- Compare reasoning with criteria, explain a correction and retain the revised evidence.
Hint and response guidance
Name the structures, quantities, system boundary and assumptions before selecting a mechanism.
Use feedback to identify a specific gap; written reasoning needs human judgment rather than keyword matching.
- Use the stated evidence and correct units.
- Explain a biological mechanism or relationship.
- Show intermediate reasoning with a labeled figure or calculation.
- State a limitation and a useful revision/test.
Submit this week
- First/revised labeled models and supported explanations.
- Assigned practice, quiz/review or exam attempt and corrections.
- Investigation records with graph, units and limitations when scheduled.
Parent / teacher weekly conference
Discuss an actual attempt before opening guidance. Use written-response criteria and notebook evidence to choose support. These home-study sessions do not certify mandated investigations or school laboratory eligibility.
- Can the learner trace a figure and explain every relevant label?
- Are variables, units and stated assumptions correct?
- Can a changed case be solved without copying a worked answer?
