Punnett squares are a diagram which biologists use to determine the probability of an offspring having a particular trait. Genetic crosses using punnett squares show how likely offspring are to inherit characteristics from their parents. In other words, it can tell you if you will or will not. Now this is a great method for predicting offspring but you can also use it for figuring out what the parents are like.
They represent dominant and recessive genes. The punnet square shows the possible genotypes of the offspring. Why is a punnett square useful?
