This web app is an intuative punnett square calculator to help you calculate allele pairs and genotype probability for an inherited trait.
- Insert allele pairs (expressed as letters; uppercased [A] for dominant alleles and lowercase [a] for recessive)
- Press 'Calculate'
- And voilà, that's it!
For this to work best, ensure you are using the same letters [Aa] (and not different letters [Ab] for example) for both of the input boxes!
