This first link is a link to a webpage where the students complete karyotypes for three patients after reading their histories.  To complete the karyotypes the students learn that chromosomes are paired based on length, centromere location, and G-banding patterns.  After completing it, they are asked to write the correct designation for the karyotype (eg: 47, XY, +21) and diagnose any chromosomal disorders that are present (eg: Down’s Syndrome).

This web page is also put out by the biology project and is a tutorial about meiosis.  At first the students can read about meiosis and watch animations of meiosis I and meiosis II.  On the next page are some brief bulleted sections comparing mitosis and meiosis (which are easily confused by students), explaining meiotic errors, and discussing how poly- and aneuploidies result.  Lastly there is a interactive quiz that the students can take online that reviews their knowledge of meiosis.

This final web page is an entertaining online quiz about plant reproduction.  It is formatted much like the “Who Wants to be a Millionaire?” game.  This would be a fun review and assessment for the students once plant reproduction had been covered in our project.

These three websites have great ideas for putting together case studies for students studying genetic disorders.
