This is a photo of a mono-hybrid punnett square. This shows that their is a 50% chance the offspring is going to be homozygous and a 50% chance of heterozygous dominant. The mother is heterozygous and so is the father. This means that their offspring might have the same alleles as the mother of father. It could either be dominant or recessive. Punnett Squares are extremely important for determining way the offspring looks and what he or she is like.
