Genetic Heredity Calculator.
Punnett Square Calculator for multiple genes
This online tool calculates Punnett Square diagram that can be used to to predict an outcome of a particular cross or breeding experiment.
It supports up to different 4 genes/traits and displays both genotype and phenotype results as well as probabilites for each of them and their combination.
Enter each parent's genotype, using capital letter for the dominant allele and lowercase letter for the recessive allele.
Use different letters to mark different genes, for example A for the first gene and B for the second one to avoid mix-ups.
If you want to use Punnett Square to calculate your child's eyes or hair color, check out Child's Traits
tool instead. It is based on Punnett Square method but uses two levels of heredity (parents and grandparents) and trait distribution statistics to improve
