Reginald Punnett, an English geneticist, developed the Punnett square to determine the potential genetic outcomes from a cross. Merriam-Webster says its first known use occurred in 1942. Heterozygous plants have a dominant and a recessive allele (alternate form) for a given trait. The Punnett squa...
