Punnet Squares are the graph that measures the possibilities and outcomes of two parents childeren. They determine the outcomes of the offspring by determining the two parents traits it has many different possibilities depending on the parents. For example if a white rabbit is Homozygous dominant and it has childeren with a Heterozygous reccesive rabbit the outcomes with be white rabbits but they won't be pure bread anymore. This is because of the rabbit being homozygous dominant it makes it impossible for the offspring to be black. but, if a brown rabbit that is heterozygous has offspring with a heterozygous black rabbit they could be half black half brown, 75% black and 25% brown, or 75% brown and 25% black. It just has many possibilities due to the parents being heterozygous.
Same with any animal if two humans have offspring and thw male is heterozygous for dark skin and the female is heterozygous for light skin they could have either dark skin babies or light skin babies it all depends on the parents traits. That is what a punnet Square does.
