Clue 1: Orient yourself
What are the main parts, stages, or choices in this model?
Use the labels and the picture's left-to-right, near-to-far, or before-and-after order. Name only what you can point to.
The question
Even if a change before birth became possible, who should decide whether the benefit is worth the risk?
Why it matters: Editing before birth could affect a future child who cannot consent, and a permanent mistake may be impossible to take back. Safety, fairness, access, and family choice are part of the science decision.
On your WebXam
You can defend an ethical position with evidence about risk, consent, and fairness.
For life
One result can have many causes; the outcome alone never tells you which.
Principle: Many roads, one ending
Try the everyday version first
Many roads, one ending
A community must decide whether to build a new bridge. An engineer can explain the design, but residents must also weigh help, harm, whose voice counts, and whether every neighborhood can use it.
Do not jump to the biology yet. Treat the picture as a small system. Track its parts, follow one change at a time, and keep more than one explanation open until the picture supplies a way to separate them.
Clue 2: Trace one change
What changes while the other parts stay the same?
Follow one object, stage, or path. Point to the first place where the situation changes instead of jumping to the ending.
Clue 3: Keep the cause open
What check would separate two explanations that still fit the picture?
List more than one explanation that still fits. Name the extra observation that would help you separate those possibilities.
Now inspect the illustration
Work from the visible evidence. A useful answer names the part of the picture that supports it and leaves unknown causes open.

Should we? The ethics of editing before birth
Discovery question
Even if a change before birth became possible, who should decide whether the benefit is worth the risk?
Many roads, one ending. The same hoped-for result can come with very different risks, so a fair decision must weigh , consent, and access.
Before this page, you should know
- A is a species studied because its biology is similar enough to ours to teach us about human development.
- Zebrafish and mice build their faces using the same core developmental program (, , and the same key genes).
Today's new idea is only
Many roads, one ending. The same hoped-for result can come with very different risks, so a fair decision must weigh , consent, and access.
Goal: Compare changes that affect one person with changes that could reach future generations, then defend a position using evidence about risk, consent, and fairness.
Know by the end
- edits affect only the treated person; edits change egg, sperm, or and pass to future generations.
- effects are unintended edits at sites that resemble the target, and they are a central concern.
- A fetus cannot consent, which raises hard questions about who decides for it and on what grounds.
- Equity and access ask who would actually get a treatment like this, and whether it would widen or narrow existing gaps.
- Bioethics weighs benefit, risk, consent, and fairness; a strong position uses evidence, not just opinion.
1
Debate prep: define the terms
Model start: affects only the treated person; changes egg, sperm, or and is passed to future generations, so its effects do not stop with the patient.
- Debate framing: be ready to explain the difference between and , and why raises the stakes.
- Debate framing: define effect and give one reason it makes editing before birth riskier.
2
Debate: the case for, the case against
Model start: For: a correction in the critical window could prevent the from forming at all, sparing years of surgery. Against: effects could cause new harm, and the work is not yet proven safe in humans.
- Argue FOR: build a two-point case that an early correction for Mateo's would be ethical, citing benefit and the critical window.
- Argue AGAINST: build a two-point case that we should not do it yet, citing risk and the fact that this is still research, not proven care.
3
Debate: consent and fairness
Model start: Because a fetus cannot consent, the decision would fall to parents and clinicians, which is why clear limits and oversight matter.
- Debate question: a fetus cannot consent, so who should decide, and what limits would you put on that decision?
- Debate question: if this treatment existed, who would realistically get it, and is that fair? Propose one rule to make access more equitable.
MedlinePlus
Open the tool Plain-language explanations of a gene or condition, written for patients and families.
When you use this: Use this when a research paper is too dense, or when you need to explain a finding to Mateo's family in everyday words.
What the screen looks like
Step by step
- 1Open medlineplus.gov/genetics and search the gene or condition (IRF6).
- 2Read the summary written in everyday words.
- 3Note the conditions the gene is linked to at the bottom of the page.
Capture these fields
- Topic: IRF6 gene
- Plain-language summary: IRF6 helps the tissues of the face join correctly before birth.
- Linked conditions: Van der Woude syndrome; nonsyndromic cleft
How to read it: Start here when a research paper is too dense. MedlinePlus gives you the gist in everyday words so you can go back to the harder source knowing what it is about.

Level 2, Collaborative
Complete a partly blank model or table and explain it.
Level 3, Independent
Make a claim from a new example or an unfamiliar entry in the same database.
Team roles
- Manager: keeps the group moving
- Recorder: writes the shared model or table
- Evidence checker: verifies each claim against the source
- Reporter: explains the group's reasoning
Process reflection
- What evidence changed your thinking today?
- What did your group disagree about, and how did you resolve it?
- What question is still unresolved?
By the end of this session, submit ONE of: a labeled diagram with a 2-sentence explanation; a claim, evidence, reasoning paragraph; a completed data table from a real database; or a one-question exit ticket using today's vocabulary.
Meets standard if your explanation correctly connects structure, timing, gene or protein function, or evidence source to Mateo's case: Compare changes that affect one person with changes that could reach future generations, then defend a position using evidence about risk, consent, and fairness.

| Accurate | The science and data are correct and match the evidence. | Mostly correct, with a small factual slip. | Key science or data is wrong. |
| Scientific reasoning (CER) | States a claim, backs it with specific evidence, and explains the reasoning. | Has a claim and evidence, but the reasoning is thin or missing. | Gives an answer with no evidence or reasoning. |
| Professional communication | Clear, organized, and labeled the way a clinician or scientist would write it. | Readable but disorganized or missing labels. | Hard to follow. |
