KARYOTYPING ACTIVITY
Name: ___________________________
For the following activity refer to the textbook and go to the following website:
http://bluehawk.monmouth.edu/~bio/karyotypes.htm.
1. Karotyping is usually done after a procedure like amniocentesis. What is an
anmiocentesis (page 171)?
2. What is the procedure for karyotyping (page 158-159)?
3. Enter the website above, view the completed karyotypes so that you see what
they look like and then complete the unfinished male karyotype. In other
words drag the chromosomes around trying to find pairs that look alike based
on their overall size and banding pattern. Then, align them so that
chromosomes number 1 is the largest pair, etc... and chromosome number
22 is the smallest pair. You should have 2 leftover unpaired chromosomes,
one large and one quite small.
When you are done print out your completed work (see the directions at the
bottom of the main page first) or trace the chromosomes with an accurate
outline and banding pattern.
4. How can karyotyping be used to determine changes in chromosome number
(page 168-169)?
5. How can karyotyping be used to determine changes in chromosome structure
like chromosome deletions, inversions, translocation, and dulications (170)?
