Reflection: Developing a Conceptual Understanding Creating Karyotypes - Section 3: Guided Practice - Creating Karyotypes


Students struggle with understanding chromosomes because they cannot see them with their eyes.  By creating an activity for students that allows them to manipulate the chromosomes to create a human karyotype, students are able to better relate to the content because they are actively engaged in the lesson.  It is important for students to make the connection between the "paper" chromosomes and the real-life DNA that we are studying in class.  The chromosomes are made of DNA which will code for specific traits in our bodies, as well as contribute specific traits in our sex chromosomes to our offspring.  This activity helps students simplify the abstract idea of chromosomes and DNA by creating the karyotype model.

Creating Karyotypes

Unit 10: Introduction to Genetics
Lesson 13 of 13

Objective: SWBAT analyze human chromosomes to determine genetic traits that will be expressed by that individual based on the genetic composition of the sample karyotype.

Big Idea: Calling all DNA detectives! Students will examine sample karyotypes to identify gender and common genetic abnormalities.
