The Million-Dollar Question
Every expecting parent asks it: *what will my baby look like?* Will they have your eyes, your partner's nose, grandma's curly hair? The answer lies in genetics — and now, increasingly, in AI.
How Genetics Determines Appearance
Your baby's appearance is governed by thousands of genes inherited from both parents. Here's how the key traits work:
Eye Colour
Eye colour is determined by melanin production in the iris. It's controlled by multiple genes, not just one:
Hair Colour & Texture
Hair colour is determined by the ratio of eumelanin (dark pigment) to pheomelanin (red pigment). Texture — straight, wavy, or curly — is determined by the shape of the hair follicle, which is also genetic.
Facial Structure
Nose shape, chin width, cheekbones, and ear shape are polygenic traits — meaning they're influenced by dozens of genes. This is why siblings from the same parents can look quite different from each other.
Can AI Predict My Baby's Appearance?
Sort of — in two ways:
1. Genetics Calculator: Our Baby Genetics Estimator uses parent traits (eye colour, hair, skin tone) to probabilistically estimate likely outcomes for your baby's features.
2. Ultrasound AI Portrait: If you already have a 3D ultrasound scan, our AI can reconstruct your baby's *actual* face from the depth data in the scan — not a guess, but a photorealistic rendering of your baby's real geometry.
The Biological Wildcards
Even with perfect genetic knowledge, some things are unpredictable:
What We Know For Sure
Your baby will be a unique combination of both of you — and probably surprise you in at least one way. That's part of the magic. But if curiosity is getting the better of you, our AI baby portrait generator lets you glimpse their face right now.
