This test is a great tool to assess a student's mastery of a Punnett Square unit. Students need to know key vocabulary terms such as dominant, recessive, homozygous, heterozygous, hybrid, purebred, phenotype, and genotype. The first section on this test is multiple choice. Then, students will have to determine phenotype based on a given genotype and be asked to determine whether a certain genotype is homozygous dominant/recessive or heterozygous. Next, students will be given several problems where they will need to construct their own Punnett Squares and answer questions about what they drew. Lastly, the test consists of a short answer response as well as an error analysis question. There is also a double-sided study guide to help prepare students for the assessment with similar content that they will be expected to know on the test.I have included an answer key for both the test and study guide for easy grading.
