Region 2.3, 2.4, and 4.2 contact bases in the -10 and -35 elements, respectively; 

sigma factor region 1.2 contacts the promoter region just downstream from the -10 element, and region 3.0 contacts the promoter region just upstream from the -10 element.

If the duplicate is redundant and does not provide a fitness benefit, it will be lost by deletion or the accumulation of loss of-function mutations.

A second fate is that a duplicate can simply retain its original function.
