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 chartautosomal dominant pedigree
See the vertical pattern expected when one altered autosomal allele is sufficient to express a trait.
Pedigree chartautosomal recessive pedigree
See how unaffected carrier parents can have an affected child when two altered autosomal alleles are required.
Pedigree chartX-linked recessive pedigree
See the characteristic pattern of affected males, carrier females, and no father-to-son transmission.
Pedigree charthow to read a pedigree chart
Read sex, affected status, partners, children, generations, and the proband in the standard order.
Pedigree chartpedigree practice problems
Practice identifying inheritance patterns from a rendered family rather than an abstract text-only question.
Pedigree chartgenetic pedigree chart
Map a genetic trait through partners, sibling groups, carriers, affected relatives, and an identified proband.
Pedigree charthorse pedigree chart
Lay out a horse’s sire and dam lines across multiple generations in a clean lineage chart.
Pedigree chartdog pedigree generator
Create a readable dog lineage chart from the animal, sire, dam, grandparents, and kennel names you provide.
Phylogenetic treephylogenetic tree maker
Turn taxa, sister groups, clades, branch lengths, and support values into a rooted phylogenetic tree.
Phylogenetic treecladogram 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
Describe each person
State sex, affected status, carrier status, partners, children, generations, and the proband.
Render the pattern
The locked Schematex engine draws standard squares, circles, fills, carrier marks, and descent lines.

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.
