Independent Assortment is crucial to understanding high school biology but is a difficult topic to teach, because it is pretty abstract. A good visual is key to teaching meiosis, chromosome genetics, and karyotypes. My students really love having this very visual and hands-on activity to help them. Use this lesson and watch a lot of light bulbs come on as your students embrace this tough concept! Each student colors a unique karyotype and you could have the students hang up their karyotypes around the room and compare how, even if they were siblings, each karyotype will be different!
I normally use this lesson at the beginning of the mitosis and meiosis unit after a 30 minute lesson on the basics of what a chromosome is, haploid vs diploid, autosomes vs sex chromosomes, gametes vs somatic cells, and what a karyotype is.
This PDF file can be printed easily on 8.5”x11” paper in landscape mode. Google Slides version is included.
Page 1: Instructions and Grandparents’ Karyotypes
Page 2: Parents’ Karyotypes and Instructions how to produce their independently assorted chromosomes in their gametes.
Page 3: Large Personalized Karyotype Diagram
Page 4: Questions for Students to answer after their coloring activity. Some are basic, some are more advanced and require longer responses.
Page 5: Challenge Question for Advanced Students, Early Finishers, or as an additional assignment/extra credit for after you teach Meiosis. It is a great way to tie meiosis back to this activity’s concepts. I like to print this separately from the first 4 pages and hand it out separately as desired.

I designed this lesson to address Next Generation Science Standard*
HS-LS3-2: Make and defend a claim based on evidence that inheritable genetic variations may result from: (1) new genetic combinations through meiosis, (2) viable errors occurring during replication, and/or (3) mutations caused by environmental factors.
