This is a very straightforward middle school-level exam that covers:
- Basic structure of DNA
- Homologous chromosomes
- Number of chromosomes in humans (23/46, this test does NOT use the terms haploid/diploid)
- Male/female sex chromosome arrangement
The test includes 23 multiple choice questions and a 2-part open response question that requires a simple analysis of a karyotype for gender and if there are any abnormalities.
This test is 3 pages long with an additional 1-sided answer sheet. You only have to make one class set of test question packets and then reuse them class to class, as it is only necessary for the students to write on their answer sheet.
