This app will help you solve basic Punnett square questions about parental crosses including blood types. Simply fill in the genotype of both organisms and the resulting Punnett square will be generated along with genotype and allele frequencies. You can also fill out expected phenotypes for a given gene to have the calculator generate phenotype frequencies. Phenotype information is automatically generated for blood types.
