Preparation:
There are enough karyotype sheets, that students can have different ones. For the normal section. Use Normal Girl and Normal Boy sheets.
For the abnormal, there are 4 sheets, so again each group can have a different one.
Sheet B - Klinefelter Syndrome (XXY)
Sheet C - Edward Syndrome (extra chromosome 18)
Sheet D - Patau Syndrome (extra chromosome 13)
Do NOT give students the abnormal sheets until the normal one is finished. This will prevent students from getting chromosomes from both sets mixed up.
This Lesson generally takes 2 class periods. 1st day - go over the lab and do the "normal" karyotype. 2nd day, do the abnormal karyotype.
