Cells in female flies have 2 X chromosomesCells in male flies have one X and one Y

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.

Chromosomes carry instructions for what cells in your body make or do (like your eye color or proteins to fight off germs)

When you grow, you need to make more cells
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
When things go wrong…..
When cells lose chromosomes, they lose information, and can cause diseases like cancer
