Final answer:

To figure out the percentage in a Punnett square, you need to follow these steps: Take the factors from the first parent and place them at the top of the square. Take the factors from the second parent and line them up on the left side of the square. Pull the factors from the top into the boxes below and pull the factors from the side into the boxes next to them. The possible offspring are represented by the letters in the boxes, with one factor coming from each parent. You can then count the number of offspring that have a certain trait and divide it by the total number of offspring to get the percentage.
