What is if my wife is short will my son be short?

As an AI language model, I am not able to predict the physical traits of a person. However, height is determined by a complex interaction between genetics and environmental factors. The height of a child is influenced by the height of both parents, as well as other factors such as nutrition and healthcare. Therefore, it is possible for your son to be short if your wife is short, but it is not a certainty. Other factors might contribute to his physical development.
