Try This

Turn to page 688, #8. Graph the frequency of the dominant allele using the same graph.

 
Answer: Remember, p = f(A) and q = f(a), so p + q = 1. Therefore, the graph for the frequency of the recessive allele will be plotted as the exact opposite. If p = 0.4, q must be 0.6. Where p = 0.85, q must be 0.15, etc.

Remember that your success in this concept depends on your ability to successfully solve problems. Practice is essential to mastery.
