What it calculates
The “Mendel Inheritance” calculator computes Chance of recessive trait (aa) in % from 2 parameters: parent 1: number of a alleles (0 = aa, 1 = aa, 2 = aa), parent 2: number of a alleles (0 = aa, 1 = aa, 2 = aa).
A lab calculation in biology and molecular biology.
Example calculation
With parameters Parent 1: number of a alleles (0 = AA, 1 = Aa, 2 = aa) = 1, Parent 2: number of a alleles (0 = AA, 1 = Aa, 2 = aa) = 1 the result is 25 %.
How to use
- Enter parent 1: number of a alleles (0 = aa, 1 = aa, 2 = aa) and parent 2: number of a alleles (0 = aa, 1 = aa, 2 = aa) — each field above is adjustable with a slider.
- Chance of recessive trait (aa) (%) is calculated automatically as you type.
- Check the worked example below to see the formula applied to real numbers.
- Copy the result or bookmark this calculator.

How is Mendel Inheritance calculated?
The Mendel Inheritance calculator computes Chance of recessive trait (aa) (in %) from parent 1: number of a alleles (0 = aa, 1 = aa, 2 = aa), parent 2: number of a alleles (0 = aa, 1 = aa, 2 = aa). Enter your values above and the exact formula is applied instantly; a worked example with real numbers is shown below.
