Karyotyping Activity
What is a zygote? Do abnormal chromosome numbers always result in Down syndrome?
What are 3 ways a doctor can get a sample of chromosomes? If we took a magnified photograph of a cell in prophase/interphase could we see the chromosomes?
3. Closure
OBJECTIVE: We will learn to
1. Analyze karyotypes and use them as a diagnostic tool to determine genetic disorders.

4. Do Now
In the Mitosis/Meiosis Trial, Martha had one extra chromosome 21. What was the concern with having an extra chromosome?
An extra chromosome 21 could lead to Down’s Syndrome once the egg is fertilized.
2. What is karyotyping?
Scientists take a photograph of the chromosomes in a cell. They organize them by size and banding pattern. Then look for possible genetic diseases in humans.

5. Purpose: look for genetic diseases.
How? Take a picture of chromosomes in a cell, organize them, place them in order of decreasing size.
