Arrange the following chromosome smears by cutting the chromosomes out. Display the chromosomes on the karyotype forms provided. Indicate on the form the sex of the individual and the abnormality if any.

Follow the web site given above to perform the Karyotype exercise on the three patients A, B and C.

Your assignment:

This exercise is designed as an introduction to genetic studies on humans. Karyotyping is one of many techniques that allow us to look for several thousand possible genetic diseases in humans. You will evaluate 3 patients’ case histories, complete their karyotypes, and diagnose any missing or extra chromosomes.

PATIENT A _______________________________________

PATIENT B _______________________________________

PATIENT C _______________________________________

An Alternative Method to Perform the Exercise Above Is Given Below

Print off the following Karyotypes. If you click on the each of the individual forms below you will be able to view a much larger image of the chromosome spreads as well as the Karyotype form. You will need 3 copies of the Karyotype Form. Using scissors you will need to cut out each of the chromosomes and glue or tape them to a Karyotype form so that you can diagnose the genetic abnormality. Be sure that you label each of the forms with the Patient and your diagnosis.
