The Hardy-Weinberg Equation How can we make predictions about the characteristics of a population? Why? Punnett squares provide an easy way to predict the possible genotypes for an offspring, but it is not practi-cal to perform a Punnett square analysis on all possible combinations of all members of a population to predict what the population might look like in the future. For that we must turn to statistics. The Hardy-Weinberg equation is a tool biologists use to make predictions about...
