If you look inside each cell, you will find chromosomes http://upload.wikimedia.org/wikipedia/commons/thumb/d/df/Drosophila_metaphase_chromosomes.jpg/800px-Drosophila_metaphase_chromosomes.jpg
Cells in female flies have 2 X chromosomes Cells in male flies have one X and one Y (plus a lot of other chromosomes) public.bay.livefilestore.com
X chromosome en.wikipedia.org Mr. Thomas Morgan studied a white eye fruit fly. It was a male. He figured out that it had white eyes because it had a different X chromosome. Fly pictures from: course1.winona.edu
Chromosomes carry instructions for what cells in your body make or do (like your eye color or proteins to fight off germs) www.genome.gov
When you grow, you need to make more cells copy Line up split How to make more cells: Take a cell, copy everything in it, split into two

Make sure each cell gets a set of chromosomes From Foley and Sprenger, 2001
Little protein machines push and pull chromosome copies
