It will determine what the baby looks like when it is born. For example we used a Punnet Square to determine if an offspring will have dark or light hair. Another example was if a offspring would have freckles or not. In my science class I had to the a project with a partner and create little paperpets. Another assignment that I had to do was that I had to fill in Punnet Squares with Genotypes like Tt or tt. Punnet Squares are also  used for flowers or plants. I am currently learning about how Punnet Squares are used for plants. I do know it works the same way with 

   In my Science class I built a little ornament that looks like DNA. I built this project out of beads and string. I had to donate a dollar so that I can do this project. The first step I did to make this project was that I had to put the beads on to the string. That part was easy. The next part I had to do was cross the beads in a certain way. I had to get one hand and cross the beads to the other. The next part was easy. I had to put more beads on to the string. The next step was that I had to cross them again. I had to repeat this a couple more times
