Baby Genetic Traits Calculator — Inherited Characteristics

Some of the most fascinating inherited traits run in families: tongue rolling, earlobe shape, handedness. Our genetic traits calculator predicts over 10 characteristics using Mendelian dominant-recessive inheritance models based on both parents' traits.

Classic Mendelian Traits

Tongue rolling (~70% can), hitchhiker's thumb (~25%, recessive), free earlobes (~65%, dominant), cleft chin (~10%, dominant). For each trait, the tool calculates probability based on whether parents carry dominant or recessive forms. Two non-rolling parents have ~30% chance of a rolling child due to incomplete dominance.

Handedness and Complex Traits

Left-handedness occurs in ~10% of people. If either parent is left-handed, child's probability increases to ~18%. Vision tendency, hair whorl direction (80% clockwise), and teeth gap have genetic components modeled with parental inputs. These traits involve multiple genes beyond simple Mendelian patterns.

Using the Results

Predictions are simplified estimates. Real inheritance for many traits involves multiple genes. Most accurate for well-characterized dominant-recessive traits. For medical-grade information, consult a professional. Continue with sensory traits or health risks.
