A researcher would like to map the location of galE and trpA genes in a new species of bacterium that appears to be closely related to E. coli. He decides to use cotransduction, and generatesnappropriate donor and recipient strains. He is disappointed when cotransduction is not seen in his experiement. What is the most reasonable explanation for this situation?

  1. His new bacterial species does not have galE or trpA genes.

  2. His new bacterial species cannot survive galE or trpA mutation.

  3. These two genes are too far apart to be mapped by cotransduction.

  4. These two genes are too close together to be mapped by cotransduction
