Karyotype Analysis
A karyotype is a tool used to analyze chromosomes of an organism by aligning
the chromosomes in pairs from largest to smallest and with sex chromosomes (X
and Y) listed last. You have been given a picture of 11 karyotypes from 11
different individuals. You should start by counting the total number of
chromosomes for each individual. Use the following terms to answer questions
about abnormalities.
Trisomy –
Monosomy –
Include the identifying term and chromosome number for each abnormality.
You should be able to determine the sex of the individual by looking at the sex
chromosomes present. If there is a Y chromosome present, the individual is
male.
Answer the questions below for each of the 11 karyotypes.

Now that you have identified your abnormalities, I will assign to you a
karyotype number for you and your group to research in your text or on the
internet. You will need to tell me (and then explain to the class) the disorder
that I have assigned to you. Please record your research below.
Karyotype assigned: __________
