AP BIOLOGY 21 Pogil Hardy Weinberg Equation Questions with Answers

The Hardy-Weinberg
Equilibrium
Why How can we make predictions about the
characteristics of a population?
?
Punnett squares provide an easy way to predict the possible genotypes for an
offspring, but it is not prac- tical 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 a
population and to show whether or not evolution is occurring in that population.

1. How many mating pairs are illustrated in Model 1?
There are twelve mating pairs.
2. Describe the parents in each mating pair in Model 1. Use terms such as
homozygous, heterozy- gous, dominant, and recessive.
One parent is heterozygous and the other is homozygous recessive.
