What percent of the population is heterozygous dominant for one of the traits in the Human Genetics project?
Materials:

Objectives:
This investigation is designed so that students can answer these questions:
What percent of the population is heterozygous dominant for one of the traits in the Human Genetics project?
Procedures:
First review an excellent sample HardyWeinberg problem from the internet. You should review the method with students and go over a couple example problems as well. Next, have students form groups of 2 students.
No Computers Method: If you do not have enough computers for each group you can have groups perform calculations using paper and a calculator. Be sure students either have a handout or have notes on how to perform the calculations. Each group should be assigned or select one of the traits from the Genetics Project to complete. Afterwards each group can report to the class their findings. Students should report the frequencies of each allele and the percent of the population that should be homozygous dominant, heterozygous dominant and homozygous recessive using the HardyWeinberg equation.
Computer method: If you do have enough computers for each group, you can use a spreadsheet that has been set up for you. Students will need to calculate the percent that is homozygous recessive (the percent that show the recessive trait) in the population. Once they fill that number into the chart, the chart will calculate the rest. Students should generate pie charts to represent the percent homozygous dominant, heterozygous dominant and homozygous recessive.
If you want to build their computer skills and have had some experience with Microsoft Excel you could have the students build the chart from scratch.
