With the help of DNA fingerprinting which can be used to determine paternity. There are three babies (Baby A, Baby B and Baby C) in a maternity ward, and three sets of confused and worried parents. (Father and Mother #1 are a couple, as are Father and Mother #2, and Father and Mother #3.) 
You do each PCR reaction on chromosome 15 and load each one into a separate well of an agarose gel, and then run the gel.

 
 Why is it that some people show three bands?

#Unit 13. Methods in Biology
  1. The more repeats you have, the longer your DNA fragment is, and longer DNA fragments migrate more slowly in gels.
  2. They are heterozygotes at this region.
  3. They are homozygotes at this region.
  4. They are heterozygotes, and possess one allele that can be cut and one allele that cannot be cut.
