What it calculates
The “Blood Type Inheritance” calculator computes Chance of group O in % from 2 parameters: mother's blood group (1 = o, 2 = a, 3 = b, 4 = ab), father's blood group (1 = o, 2 = a, 3 = b, 4 = ab).
A lab calculation in biology and molecular biology.
Example calculation
With parameters Mother's blood group (1 = O, 2 = A, 3 = B, 4 = AB) = 2, Father's blood group (1 = O, 2 = A, 3 = B, 4 = AB) = 1 the result is 41.77 % (Parents' genotypes are estimated from allele frequencies (Europe): O 0.66, A 0.26, B 0.08, Rh d 0.40).
How to use
- Enter mother's blood group (1 = o, 2 = a, 3 = b, 4 = ab) and father's blood group (1 = o, 2 = a, 3 = b, 4 = ab) — each field above is adjustable with a slider.
- Chance of group O (%) is calculated automatically as you type.
