The appearance of a baby is determined by complex genetics involving a mix of genes from both parents. While many traits like eye color, hair color, and complexion are influenced by the parents' genes, predicting exactly what a baby will look like is not precise due to the vast genetic variation and environmental effects. For example, eye color depends on multiple genes controlling pigments, and hair color can change over time due to genetic and environmental factors. Babies can also inherit traits that neither parent visibly has, coming from family ancestry. There are AI-based baby face generator tools that create fun visual predictions based on photos of the parents, but these are for entertainment and do not guarantee accuracy in predicting the child's actual appearance. Overall, the baby's look is a unique combination of genetic inheritance plus some unpredictable variations, so while parents may have a general idea based on their traits and family history, the exact appearance will only be revealed after birth.
