Reflection: Developing a Conceptual Understanding Karyotyping: A Look at A Cell's Chromosomes - Section 3: Instructional Input/Student Activities


Students engaged and hard at work. The basic gist of this assignment is to get a feel for the categories of chromosomes: autosomes v. sex chromosomes and male v. female sex chromosomes

This student's work shows the differentiation between paternal (blue) and maternal (pink) chromosomes and the number designations for the twenty-three pairs, making a distinction for the last pair (sex chromosomes).

Karyotyping: A Look at A Cell's Chromosomes

Unit 4: 3) Genetics ("Identity & Change")
Lesson 1 of 10

Objective: 1. Multicellular organisms have a hierarchical structural organization, in which any one system is made up of numerous parts and is itself a component of the next level. (HS-LS1-1) 2. Enduring Understanding #1 (Most of the cells in a human contain 46 chromosomes: 2 x 22 autosomes and 1 x 2 sex chromosomes = 46 total).

Big Idea: The chromosomes of an organism's cells, in part, define certain aspects of its nature.
