DNA polymorphisms are regions of DNA that vary greatly (are polymorphic) between individuals. These polymorphisms are frequently used to obtain a 'DNA fingerprint of individuals.

Using their own hair or cheek cells as sources of DNA, students will isolate human DNA and compare DNA polymorphisms between individuals.
