Solution-How does gel electrophoresis sort dna fragments

1. How does gel electrophoresis sort DNA fragments?

2. If each individual has such a small amount of DNA, how do the bands on the gel contain enough DNA to be visible?

3. Many genes only have a few possible alleles. For example, humans only have a few eye colors and only four blood types. How can DNA tests definitively identify individuals when many men have brown eyes or type A blood?
