Creating Twins & Multiples

GenogramAI supports twin and multiple birth documentation with standard genogram notation—V-shaped connections for all multiples, plus a horizontal bar for identical twins.

Two Twin Types

• Fraternal (Dizygotic) - V-shape only. Developed from separate eggs.
• Identical (Monozygotic) - V-shape + horizontal bar. Developed from one egg.
