Question

Where do you put the parents' genotypes when you're doing a Punnett Square?


Outside the box on the top and left


Inside the box

Answer 1

In a Punnett Square, the parents' genotypes are placed outside the boxes: one parent's genotype is written along the top, and the other parent's genotype is written along the left side. Each box within the square is then filled in with the combinations of the alleles from each parent to show the possible genotypes of the offspring.
