Pick each parent's trait to see what the baby might inherit.
Based on classic Mendelian genetics (dominant / recessive). Real looks depend on many genes plus environment, so treat this as a fun, educational estimate — not a real prediction.
Every parent wonders whose eyes, hair, or smile a baby will inherit. Baby Genes is a free baby appearance predictor that turns that question into a simple, visual game. Pick each parent's dominant or recessive trait for nine classic features — eye color, hair color, hair type, dimples, freckles, earlobes, tongue rolling, widow's peak, and thumb shape — and the tool instantly shows which parent the child is more likely to resemble, with a probability percentage for every trait and an overall look-alike score.
The logic is built on classic Mendelian genetics. Each parent carries two copies of a gene, one from each of their own parents, and passes one copy on at random. A dominant trait needs only one copy to show up, while a recessive trait needs two. That is why two brown-eyed parents can sometimes have a blue-eyed baby, and why some family features skip a generation. When one parent is dominant and the other is recessive, the child usually shows the dominant trait about 75% of the time; when the pairs are mixed, the odds drop to 50/50.
This baby genes predictor is designed to be fun and educational. It is a great conversation starter for expecting parents, a quick demo for a school science class, or just a playful way to imagine the future. The tool updates live as you tap, so you can experiment with different combinations and watch the percentages change. Because the real world is more complicated, the results are a simplified estimate rather than a medical prediction.
Each trait follows a dominant / recessive pattern in this calculator:
It compares the dominant and recessive trait choices you make for each parent using classic Mendelian inheritance, then shows a probability for every trait and an overall look-alike score.
The results are educational, not medical. Real appearance is polygenic — many genes and the environment shape a child's features — so treat the percentages as a fun, simplified estimate.
