A punnet square is a big square with four smaller squares in it. The point of a punnet square is to tell what kind of trait the offspring will get, and the trait the offspring gets is based on dominant. Say that there is a dominant trait for dark hair and a recessive trait for light hair. If the dad has homozygous dominant DD for dark hair and the mom is homozygous recessive for light hair. Then the child will have dark hair because no matter what kind of trait the dominant is paired up with, the dominant trait will always show.
But let's say that they are both Dd then the child will be either DD Dd r dd. Then what if one is dd and Dd the child will either be Dd or dd. I've done some punnet squares in my life as well, in fact yesterday we had a test on punnet squares, dominants and traits. I'm pretty sure that I passed the test with at least a B or higher if I didn't then I will be really disappointed with myself. But any way the reason for punnet squares is to determine the trait of an offspring based on dominants. In case you were wondering what kind of vocabulary I used in here and what they mean then here they are. Homozygous means that it is the s
