Ways to predict what your baby might look like include learning about genetics or visiting websites that analyze photos of you and your partner and then synthesize a potential baby's photo. Dominant genes are more likely to express themselves than recessive ones, explains Parents.com.
If you know the parents' and other family members' eye and hair color, height, weight, and other features, you can guess which features a baby might have. Dark hair and eyes are dominant over light colors. You can guess at height by adding the father's and mother's height and figuring the average. Add a couple of inches if the child is a boy. Subtract a couple of inches if the child is a girl. Results may vary by child, notes Parents.com.
BabyPictureMaker.com and Make Me Babies are websites that allow uploads of photos of parents-to-be and analyze them to determine how their child might look. Both of these sites are free to use.
