Teaching about crossing over and nondisjunction can be challenging without good diagrams. This package contains full page diagrams and two reading to explain them!
I strongly suggest using my FREE Chromosome Structure Reading/Diagram Page activity
and my Mitosis Diagram Activities
and my Meiosis Diagram Activities
These activities are also available in a money saving bundle!
This activity bundle includes 3 nondisjunction diagram pages and 2 crossing over diagram pages and 2 reading pages. See my preview to see more details!
Unique Features of this Activity Pack:
In all diagrams, I represent the whole chromosome (both arms) as a straight rounded shape, instead of the normally bent “X” shaped chromosomes. This really helps students to understand what the chromatid actually is and what separates during mitosis. So often students confuse “chromosome arm” with “chromatid”. Each chromatid has 2 chromosome arms, which is why I draw the chromosomes in these diagrams the way I do.
