Lab Exercises

Exercise 1
Your instructor has provided you and a group of your classmates with the stained
chromosomes from person Z. Follow these steps to create person Z’s karyotype and answer the
questions.
Step 1
Match each chromosome to its homologous partner (remember to look for similar size,
centromere location, and staining patterns).
Step 2
Arrange the chromosome pairs in order from largest to smallest.
STEP 3
Match the sex chromosomes provided by your instructor.
1. How many autosomes does person Z have? How many sex chromosomes?
2. Is person Z male or female? Why?
Exercise 2
Work with a group of your classmates to review the two karyotypes and answer the questions.
Note the karyotypes provided depict single chromosomes, rather than homologous pairs.
