Interactive Karyotype Activity [new] Guide
This paper-based interactive karyotype activity allows you to simulate a clinical genetics lab. You will act as a cytogeneticist to organize chromosomes and diagnose a chromosomal disorder. Activity Overview
// display each chromosome inside slot slotChromosomes.forEach(chrId => const chr = chromosomes.find(c => c.id === chrId); if (chr) const miniCard = document.createElement('div'); miniCard.className = 'chromosome-card'; miniCard.style.width = '52px'; miniCard.style.cursor = 'pointer'; miniCard.style.background = '#fff6e0'; miniCard.setAttribute('data-id', chr.id); miniCard.innerHTML = ` <div class="chr-icon">$getChromosomeIcon(chr.type)</div> <div class="chr-label">$chr.type === 'X' ? 'X' : (chr.type === 'Y' ? 'Y' : chr.type)</div> `; // allow to remove from slot by doubleclick miniCard.ondblclick = (e) => e.stopPropagation(); removeChromosomeFromSlot(chr.id, slotNumber); ; chromosomesContainer.appendChild(miniCard);Ensuring there are 46 chromosomes (23 pairs) in a standard human cell.

- Prepare the materials: Obtain simulated chromosomes, karyotype templates, or online platforms and apps.
- Introduce the concept: Review the basics of genetics and karyotypes with the students.
- Conduct the activity: Have students work individually or in pairs to create a karyotype.
- Facilitate discussion: Encourage students to discuss their findings and results.
- Assess student learning: Evaluate student understanding through quizzes, class discussions, or written assignments.
3. Materials Needed
- Option A (Physical/Classic): Printed sheets of scrambled chromosomes, scissors, glue/tape, a "Karyotype Reference Sheet" (showing normal arrangements).
- Option B (Digital): Computers/tablets with access to an online karyotyping simulator (e.g., University of Utah’s "Genetic Science Learning Center" or Biology Corner).
