Karyotype Activity [updated]: Interactive

: The 23rd pair determines biological sex (XX for females, XY for males). The Power of Interactive Learning

These conditions involve an abnormal count of the X or Y sex chromosomes, often presenting milder symptoms than autosomal trisomies.

Developmental delays, distinct facial features, heart defects. Trisomy 18 (Three copies of chromosome 18)

Assessment Examples

: Writing standardized micro-biology notations (e.g., 47, XY, +21). : The 23rd pair determines biological sex (XX

Three chromosomes at position 18; often leads to severe developmental delays. XXY (Sex Chromosomes)

Students complete one "Normal" patient and one "Abnormal" patient.

: A segment of one chromosome breaks off and attaches to an entirely different chromosome. Best Practices for Teachers Implementing the Activity Trisomy 18 (Three copies of chromosome 18) Interactive

Present students with a "messy" image—chromosomes scattered randomly, as they would appear under a microscope during metaphase.

: Unique horizontal stripes produced by chemical stains (like Giemsa) that reveal specific gene locations.

In the past, students and researchers learned karyotyping by physically cutting out pictures of chromosomes from a photograph and pasting them onto a grid. Today, the digitalizes this process. It provides an engaging, hands-on way to explore cytogenetics, understand chromosomal structures, and diagnose genetic conditions. What is a Karyotype?

Line up the pairs from largest to smallest (Pair 1 to Pair 22). Place the sex chromosomes ( ) at the end as the 23rd pair. 3. Analyze the Results Count the total number of chromosomes.
