Meiosis
Study this picture. Notice how a cell with four chromosomes turns into four different cells, each containing two chromosomes.

Crossing Over
Remember, the steps of Meiosis are similar to the steps to Mitosis. The major differences is that "Crossing Over" of the DNA occurs in Meiosis.
During Prophase 1 and Metaphase 1 of Meiosis, the DNA next to each other can SWITCH chromosomes, making a completely new strand of DNA.

Meiosis results in half the original DNA
Each new sperm or egg cell has a different set of DNA, which is why you are different than your siblings.
