Directions: Use the Hardy-Weinberg equation to calculate the
predicted genotype frequencies for each population scenario below.
Place your calculations and data in the spaces provided. Once you
have calculated the frequencies, answer the corresponding
conclusion questions. After completing all three scenarios, analyze
your responses to each and answer the final conclusion
question.
In the year 2850, humans successfully colonized Mars. The
Martian modules that were constructed could hold only a small
population of people. It is now a century later, and the population
on Mars has grown to 600 people. Of the current Mars population, 45
people express the recessive phenotype for phenylketonuria (PKU)
syndrome (pp genotype).

Conclusion Questions Use this information to help you answer the
following questions: The original population’s actual genotype
frequencies were: PP – 0.53, Pp – 0.25, pp – 0.22.
1. Is the current population in Hardy-Weinberg equilibrium? Yes
or No
2. Is the current population evolving? Yes or No
3. If the current population is evolving, what type of effect is
responsible for genetic drift?
