Understanding genetic health risks is a natural parental concern. Our estimator provides educational estimates for carrier probabilities based on both parents' known or suspected status. Covers cystic fibrosis, sickle cell disease, thalassemia, color blindness, hemophilia, PKU, Tay-Sachs, and more.
Autosomal recessive (CF, sickle cell): both parents must carry the gene. Two carriers: 25% affected child, 50% carrier, 25% unaffected. X-linked recessive (color blindness, hemophilia): affects males more — carrier mother gives 50% affected sons. Autosomal dominant: one copy sufficient. The tool models each type with separate boy/girl risk estimates.
Cystic fibrosis (1 in 25 carriers in Caucasians), sickle cell (1 in 12 in African Americans), thalassemia (Mediterranean/South Asian), color blindness (~8% of males), hemophilia (1 in 5,000 males). Each shows inheritance type, severity, carrier frequency, and calculated risk.
This is educational entertainment only. Cannot account for incomplete penetrance, variable expressivity, de novo mutations, or epigenetic factors. Never substitute for professional genetic counseling or prenatal testing. For concerns, consult a licensed genetic counselor. For fun predictions: eye color, sensory traits. For your own traits: uniqueness calculator.
