Exercise
1. As an introduction, students will determine the phenotypes of representative
alleles and record them on the worksheet.
2. The student will then determine the ratio of offspring of a specific
genotype.
3. Using the results of the test cross, the student will use coins to calculate
the percentage or ratios from the test cross and compare the predicted to the
actual results.
4. Students will answer inquiry based questions related to the worksheet.
