Description
This remote learning ready, google slides lesson has students examine sources of error during meiosis, then challenges them to examine karyotypes and determine what syndromes can result from unusual arrangements of chromosomes.
Students begin by illustrating a complete model of meiosis, including independent assortment and crossing over. Students are then asked to rate their comfort with these concepts before they move on. If they are comfortable, they then draw pictures of what meiosis would look like if non-disjunction errors occurred during division 1 or division 2 of meiosis, and read about what mistakes can happen during crossing over.
Students next examine 7 different karyotypes (2 healthy and 5 from individuals with chromosomal syndromes.) Students examine the chromosomes to determine what is unusual. By doing this, they make themselves a "karyotype key."
Once the key is completed, students examine amniocentesis results in order to determine if 6 pregnancies are healthy.
Thank you, and happy teaching!
