Baby Appearance Predictor — Physical Feature Estimates

Beyond eye and hair color, parents wonder about face shape, dimples, freckles, and body build. Our appearance predictor estimates these characteristics using known dominant-recessive inheritance patterns and polygenic blending models.

Facial Feature Inheritance

Face shape, nose type, and lip fullness are polygenic traits showing blending patterns. Children's features typically fall between both parents. The tool models contributions from each parent to produce probability distributions for facial characteristics.

Dimples and Distinctive Features

Cheek dimples are dominant — one dimpled parent gives ~50% chance. Both parents dimpled: ~75%. Freckles are MC1R-linked and dominant. Widow's peak is dominant (~35% of population). The calculator uses each specific parental combination to estimate probabilities for these distinctive features.

Height and Body Build

Height prediction uses the mid-parental formula: averaging parents' heights with sex adjustments (+6.5cm for boys, -2.5cm for girls), providing min/avg/max estimates within ±8cm. Body type is 40-70% heritable. These are fun estimates — real inheritance involves hundreds of genetic variants. Explore genetic traits or sensory traits.
