Question
A new series of rII mutations in the virulent phage T4 has been isolated, and
the results of phage recombination experiments between all twelve of the
new mutations are listed below:
Draw a inear genetic map showing the location of all point mutations and
the frequency of recombination between adjacent mutations. Describe the
location and extent of all deletions.

Understanding pathogen infectivity and virulence requires combining insights from epidemiology, ecology, evolution and genetics. Although theoretical work in these fields has identified population structure as important for pathogen life-history evolution, experimental tests are scarce. Here, we explore the impact of population structure on life-history evolution in phage T4, a viral pathogen of Escherichia coli. The host
