Baby Genetics Calculator

How to Use the Baby Genetics Calculator

The Baby Genetics Calculator is a helpful tool designed to provide genetic predictions about a baby’s potential traits based on parental characteristics such as eye color, hair color, and height. Follow this step-by-step guide to use the calculator efficiently.

Step 1: Input Mother’s Information

• Select Mother’s Eye Color: Choose an option from the dropdown menu that best matches the mother’s eye color. The available options are Brown, Green, Blue, and Hazel.
• Select Mother’s Hair Color: Choose the mother’s hair color from Black, Brown, Blonde, and Red from the dropdown menu.
• Enter Mother’s Height: Input the mother’s height in centimeters. The height must be between 140 cm and 200 cm. This field is mandatory, so ensure it meets the limits provided.

Step 2: Input Father’s Information

• Select Father’s Eye Color: From the dropdown menu, select the eye color that best matches the father’s eye color. The options available are Brown, Green, Blue, and Hazel.
• Select Father’s Hair Color: Choose the father’s hair color from Black, Brown, Blonde, and Red from the dropdown list.
• Enter Father’s Height: Input the father’s height in centimeters. Ensure the height is within the range of 140 cm to 220 cm, as this field is required.

Step 3: Reviewing Predicted Results

Once all the required inputs are provided, the calculator will generate predictions based on the calculations configured in it. Here are the predicted results you’ll receive:

• Predicted Adult Height (Boy): This figure is calculated with the formula ((fatherHeight + (motherHeight * 1.08)) / 2) and expressed in centimeters with one decimal point accuracy.
• Predicted Adult Height (Girl): Calculated using the formula ((motherHeight + (fatherHeight * 0.923)) / 2), this predicts the potential adult height for a girl, displayed in centimeters to one decimal point.
• Probability of Brown Eyes: This probability is calculated based on the formula (motherEyeColor == 'brown' || fatherEyeColor == 'brown') ? 0.75 : 0.25 and displayed as a percentage.
• Probability of Blue Eyes: Provided as a percentage, this considers eye color combinations using the logic (motherEyeColor == 'blue' && fatherEyeColor == 'blue') ? 0.99 : ((motherEyeColor == 'blue' || fatherEyeColor == 'blue') ? 0.50 : 0.01).
• Probability of Dark Hair: Using the calculation ((motherHairColor == 'black' || motherHairColor == 'brown') && (fatherHairColor == 'black' || fatherHairColor == 'brown')) ? 0.90 : ((motherHairColor == 'black' || motherHairColor == 'brown' || fatherHairColor == 'black' || fatherHairColor == 'brown') ? 0.70 : 0.25), this probability is expressed as a percentage.
• Probability of Blonde Hair: Calculated with (motherHairColor == 'blonde' && fatherHairColor == 'blonde') ? 0.80 : ((motherHairColor == 'blonde' || fatherHairColor == 'blonde') ? 0.50 : 0.10), this probability is shown as a percentage.

By following these steps, you can accurately use the Baby Genetics Calculator to anticipate a potential range of genetic traits for a baby based on parental characteristics.
