A real visitor’s prompt and pedigree chart

The original French prompt and generated chart, shown without rewriting. The chart adds two unaffected individuals not mentioned in the prompt: II-1 and II-5 (the partner of II-2). Check the result against your source.

A visitor typed

Description de l’arbre généalogique (Document 1) Génération I : - L’individu I₁ est une femme atteinte de la maladie. - L’individu I₂ est un homme sain. Génération II : - Les individus II₂ et II₃ sont des hommes atteints. - L’individu II₄ est une femme saine, mariée à l’individu II₃. Génération III : - Descendance de II₂ : une fille atteinte (III₁) et deux garçons sains (III₂ et III₃). - Descendance du couple II₃ × II₄ : une fille atteinte (III₄) et deux garçons sains (III₅ et III₆).

What you can do with the download

SVG and PNG

Download SVG for a scalable vector image or PNG for a flat picture. To change the generated content here, revise the description and generate again.

Editing after download

The PNG has no editable shapes. Open the SVG in Inkscape to edit vector objects. To change relationships, connections or layout here, revise the description and generate again.

Limits worth knowing first

30 requests / hour

Per IP address. A shared network shares the limit. All attempts count, including failures. At the cap, wait an hour and try again.

2,000 characters

Maximum input length. Shorten the description to the details that matter.

20,000 per 24 hours

Site-wide request capacity over a rolling 24 hours. If it is reached, try again in an hour.

0 accounts

No signup or personal history. Download your result before closing the tab.

  • Check each individual, relationship and affected status against your source. The chart does not establish an inheritance pattern or a medical diagnosis.

What happens to what you type

  1. We keep it

    Your description, generated output, full response, hashed IP address and operational metadata are saved so we can enforce limits and check quality. We don’t delete them automatically yet; email us to request deletion.

  2. Good pedigree charts may appear in Examples

    Eligible prompts and results are shown publicly by default with the original prompt, until removed. Don’t enter names, client data or anything confidential.

  3. We never ask who you are

    No account, name, email or payment.

Scenario and reference pages

See the inheritance pattern, then make your own

Every teaching page begins with a rendered, hand-checked example and the rule it demonstrates.

Pedigree chart

pedigree chart

A pedigree chart uses standardized shapes, fills, and descent lines to show a trait across generations.

Pedigree chart

autosomal dominant pedigree

See the vertical pattern expected when one altered autosomal allele is sufficient to express a trait.

Pedigree chart

autosomal recessive pedigree

See how unaffected carrier parents can have an affected child when two altered autosomal alleles are required.

Pedigree chart

X-linked recessive pedigree

See the characteristic pattern of affected males, carrier females, and no father-to-son transmission.

Pedigree chart

how to read a pedigree chart

Read sex, affected status, partners, children, generations, and the proband in the standard order.

Pedigree chart

pedigree practice problems

Practice identifying inheritance patterns from a rendered family rather than an abstract text-only question.

Pedigree chart

genetic pedigree chart

Map a genetic trait through partners, sibling groups, carriers, affected relatives, and an identified proband.

Pedigree chart

horse pedigree chart

Lay out a horse’s sire and dam lines across multiple generations in a clean lineage chart.

Pedigree chart

dog pedigree generator

Create a readable dog lineage chart from the animal, sire, dam, grandparents, and kennel names you provide.

Phylogenetic tree

phylogenetic tree maker

Turn taxa, sister groups, clades, branch lengths, and support values into a rooted phylogenetic tree.

Phylogenetic tree

cladogram maker

Build a branching cladogram that emphasizes shared ancestry and nested groups without implying a linear ladder.

Process

From family facts to standard pedigree notation

01

Choose the question

Open a genetics, animal pedigree, cladogram, or phylogenetic-tree page.

02

Describe each person

State sex, affected status, carrier status, partners, children, generations, and the proband.

03

Render the pattern

The locked Schematex engine draws standard squares, circles, fills, carrier marks, and descent lines.

04

Check and export

Confirm the inheritance rule, then download SVG or PNG or refine it in ChatDiagram.

Details

Questions, answered plainly

Are the inheritance examples checked?

The launch examples for autosomal dominant, autosomal recessive, and X-linked recessive inheritance are hand-authored and tested against the stated rule.

What is the difference between a pedigree and a genogram?

A pedigree tracks inheritance using genetics conventions. A genogram records broader family and emotional relationships; those tools live on GenogramMaker.ai.

Can it make animal pedigrees?

Yes. The pedigree engine works for horse and dog lineage charts as well as human genetics, while the phylo engine handles species-level trees.

Is it free for classroom use?

Yes. There is no signup, payment, or watermark. Hourly fair-use limits apply to generation requests.
