How would the environment impact a multifactorial trait like height in someone with normal genetic variation? How would environment impact someone with a mutation that results in dwarfism?

Explanation:

On someone with a normal genetic variation, the environment helps them adapt and pushes for the evolution of the traits that will help that species increase their chances of survival in future generations. This includes traits such as height, thus increasing this trait so that the species is able to reach food in higher places or reach higher places in order to find shelter. This does not have the same effect when dealing with a certain genetic mutation such as dwarfism since the mutation targets a specific value for these traits and is not affected by its environment.
