: Pairs 1 through 22 are identical in both males and females. They are ordered largest to smallest.
Structural changes where pieces of chromosomes are moved or missing. Conclusion
It can be difficult to conceptualize an extra or missing chromosome. Physically moving a third chromosome into pair 21 makes the concept of trisomy instantly clear. 3. High Engagement and Gamification
Suggest to check understanding after the activity. Karyotyping Activity - The Biology Project Interactive Karyotype Activity
Students match chromosomes based on size, centromere position, and distinct banding patterns.
: Provide a printed sheet of "mixed" chromosomes, scissors, and a template for manual arrangement.
: No clean-up, automatic grading, and highly accessible. : Pairs 1 through 22 are identical in both males and females

A missing chromosome (e.g., Turner Syndrome , where a female has only one X chromosome).
You can find a wide array of materials on the following platforms:
Using web-based flash or HTML5 programs, students drag and drop chromosome images on a screen.
: Platforms like Google Slides have become a favorite for creating simple, accessible karyotyping exercises. Students can drag individual chromosome images into a grid, matching homologous pairs by size and banding pattern. These activities are highly efficient, eliminating the mess of paper and allowing for instant diagnosis and feedback.
: Humans have 46 chromosomes, arranged into 23 pairs.
