The observation that the corresponding genes travel together with the head and tail genes is less easily explained but may reflect well-documented interactions among recombination proteins and DNA replication initiation and between recombination proteins and DNA packaging [34]. As a result, if recombination generates a hybrid by joining parts of head gene sets from two different phages, the recombinant would be non-functional and so lost from the population, even though each of the genes was fully functional in its original context.
