Eye-color predictor
Brown + blue = ? A simplified Mendelian guess.
What it does
The Eye-color predictor takes two parent eye colors (brown, green, blue) and sketches approximate chances for the baby using a simplified Mendelian model. It is transparent about the simplification: real inheritance is more complex, and hazel and other shades are folded into the three buckets. Entertainment only — not a genetic test, not medical advice. Results copy, share, and print.
