Genetic Fact

Hair type follows "Incomplete Dominance." If one parent has very curly hair and the other has poker-straight hair, the baby has almost a 100% chance of having wavy hair—a physical blend of both parents!

Beyond the Punnett Square.

While simple charts (like eye color) give us a good estimate, human genetics are far more intricate than most textbooks describe. Over 16 different genes influence eye color alone!

Recessive 'Surprises'Both parents with brown eyes can have a blue-eyed baby if they both carry the recessive blue gene from their own ancestors.

How to use this tool

  • 1
    Check parent traits carefully
  • 2
    Observe grandparents if possible (as a hint for recessive genes)
  • 3
    Remember: Every baby is a unique genetic masterpiece!
