Environmental factors can influence the gene expression in some organisms. Using a specific example, explain how a lighter shade of a color can affect the gene expression in an organism where lighter shading affects the phenotypes of the organism. First answer will mark as the brainliest

An example is the drop of white-colored moths and an increase in dark-colored moths in London after the industrial revolution. Because darker-colored moths could camouflage well in the sooty environment (due to industrial emissions), they were preyed less by their predators. White-colored moths stood out and due to being preyed more their numbers declined over generations - because they wouldn't survive long enough to reproduce and pass their genes to the next generation. The predominant color for the moths' population became dark color.
