What do you mean? Are you talking about mutation in first generation or mutation in second generation? First generation means Scott suddenly gains an extra chromosome from working 23 hours a day in an alien slave labor camp. Second generation is when Scott remains normal but for some darn reason Scott Junior gains an extra chromosome.
Anyhow, the answer is no to either case. I'm not talking about gaining an extra chromosome. I'm talking about mutation in general. Any kind of mutation that is observed is a result of randomness not physical exersion.
However, slavery might result in artificial selection that would result in certain characteristics appearing more frequently than normal. For example, if Scott happens to be big and strong, Scott's master would certainly send him off to mate with Sarah, April, Christine, and a whole bunch of other female slaves so Scott's master could have more slaves that are big and strong like Scott.
Hate world.
Revenge soon!
