Monohybrid Cross: Dihybrid Cross; Complete and Incomplete Dominance; The most common Punnett square is that of a monohybrid cross. In a monohybrid cross, the character (s) being researched are governed by two or more variations for a locus or site in a gene. The hybrid offspring will exhibit only the dominant trait in the phenotype.. For example, if you are asked to give a phenotype ratio using a Punnett square, your ratio will be different if the trait shows incomplete dominance or co-dominance than if your trait shows complete dominance.
