Is the Pedigree Chart Maker free, and do I need to sign up?

The whole workflow is free and needs no account: enter or import family rows, preview the diagram, run relationship checks, and download SVG or PNG. It uses no credits and adds no watermark or paid export step. You are still responsible for checking every relationship and symbol before you use the chart.

What can a family Pedigree Chart Maker show beyond a basic family tree?

It shows relatives grouped by generation, with parent-child lines, sex symbols, affected or carrier status, proband arrows, deceased markers, and optional genotype labels. Start from the Family History template for a three-generation view, then check each relationship before you save or share the exported chart.

How do I add genotypes in a genetic Pedigree Chart Maker?

Type a verified genotype such as AA, Aa, aa, XAY, or XAXa into the optional Genotype column for each relevant person. The chart prints it under the member's ID and name. The tool only displays what you enter. It does not infer, validate, or diagnose genotypes from family relationships.

What is a proband in a pedigree chart?

A proband is the family member whose condition first brings the family to attention, and the person a pedigree investigation starts from. Enter proband in the Flags column for one person, and the chart draws an arrow beside that symbol. The flag marks the reference person only. It does not diagnose anything or calculate genetic risk.

How do I build a 3 generation pedigree template?

Give each person an ID that starts with I, II, or III for the first, second, and third generation, then enter each child's father and mother IDs. The chart arranges the three generations automatically. The relationship check flags any parent placed in the same generation as, or after, their child.

How should I use a medical Pedigree Chart Maker responsibly?

Use the Clinical History template to organize relationships, selected traits, carrier status, the proband, deceased relatives, and verified genotypes before a professional review. A medical Pedigree Chart Maker should support documentation, not diagnosis. This tool does not confirm inheritance patterns, calculate recurrence risk, or replace a qualified genetics professional.

How do I use a free online dog Pedigree Chart Maker?

Choose the Animal Breeding template, then replace the sample sire, dam, offspring, carrier status, and genotype rows with your verified records. The free online dog Pedigree Chart Maker arranges the generations and exports SVG or PNG without sign-up. It gives you a consistent reference diagram but does not judge breeding suitability or genetic risk.
