Tool used to predict results in mendelian genetics; Shows all the ways in which alleles can combine. Using a punnett square properly will enable you to figure out potential offspring for any possible morphs that are genetically homozygous will always produce offspring that are morphs, which is why they the punnett square is an extremely useful tool for understanding odds and probabilities for.
