During salutary neglect why did great britain not enforce its own laws on the colonies?

The policy of 'Salutary Neglect' lasted from the early 1600's to the 1760's and avoided strict enforcement of parliamentary laws - British officials in the colonies were basically allowed to turn a 'blind eye' to trade violations - they neglected to enforce the law.

genetics is the study of how dna works, the methodologies defining the new recent technologies allow scientist to have a panoramic view of the entire dna landscape, especially how genomes interact with their environment, including off course, factors outside their organisms.

thus is very possible the existence of both scenarios, where populations of isolated individuals have different genetic traits, and share traits related to genetic mutation, due rats can easily travel overseas using human transport channels. so scientists could get a vast number of data, including human interaction, evolution of rodents, health development, spread of infections, development of new organisms, how genomes evolve in different environments and so on.
