Paul Andersen explains how linked genes behave and how linked genes were discovered. He shows how linked genes would be reflected in a dihybrid cross using a fruit fly simulator. He uses chromosome-based punnett squares to explain why the frequency of recombination is less that 50%. The actual crosses discovered by Thomas Morgan and Alfred Sturtevant are included.
