Pedigree chart templates
Every template opens as a brand-new, editable project stored only in your browser — then rename, re-shade, or rebuild it however you like. Previews below are the actual exported charts.

Frequently asked questions about templates
Can I edit and customize these templates after opening them?
Yes. Opening a template creates an independent, local copy in your browser with fresh IDs. You can rename individuals, add spouses or siblings, change phenotypes, and auto-arrange the layout.
Are these templates free to export for classroom or commercial use?
Yes. All templates are 100% free with no account or paywall. You can export vector SVGs, high-resolution PDFs, and PNGs for school assignments, publications, or clinical documentation.
What is the easiest template for a beginner to start with?
For personal family health tracking, we recommend the Three-Generation Pedigree. For genetics students, start with the Autosomal Dominant or Autosomal Recessive templates to practice foundational inheritance rules.
