A child inherits 50% of their DNA from each parent, but because genes shuffle randomly through genetic recombination, siblings can look completely different from one another while sharing the same genetic parentage.
Facial characteristics are inherited from both parents and are polygenic, meaning they are shaped by multiple genes acting in concert. Our generator simulates facial structure by pairing parental inputs with genetics models representing dominance and recessive ratios, combined with a random gene reshuffle.
Face shapes like Oval and Round are typically dominant traits, while more angular variations like Square can be recessive, meaning they require two copies to appear visibly.
Skin pigmentation is controlled by more than 100 genes that regulate melanin production. Children of parents with different skin tones typically display intermediate shades.
Eye size and shape are determined by bone structures and fatty deposits around the eyes, which are governed by a complex set of developmental genes inherited from parents.
During fertilization, genetic recombination ensures every baby gets a unique combinations of traits. This random shuffle is simulated in our avatar results engine.
Our generator uses basic Mendelian dominance rules and polygenic probability to estimate features. Because human genetics has billions of combinations, this simulator is strictly educational and serves as a fun approximation, not a photo projection.
No. True appearance depends on structural development and many environmental factors. This tool visualizes the likely combination of physical features (phenotype) that your baby could express.
Our engine generates a personalized baby portrait using inline SVG vectors styled in real time based on the skin, eye, hair, and face shapes calculated from the parents' genetics.
