If it's environmental, it's not genetic mutations. If it's a genetic mutation, whatever the cause for the mutation (radioactivity, chemical, etc) it's still random and the outcome cannot be predicted. It didn't became orange on purpose.

    It's ALL genetic mutation, no matter what the source. You meant that if it isn't environmental, it's spontaneous, just the genetic roulette wheel taking a weird spin, instead of being influenced by some outside force.

    There is no such thing like a force skewing genetic mutations in a specific direction. It's a stochastic process. You DNA is hit by an ionizing radiation and a modification ensue which can be anything and this happens randomly. Most of the time dysfunctional cells will be destroyed by the immunity system otherwise if the cells proliferate you got cancer. If it is DNA from reproduction cells, you may get a mutant or a nonviable embryo, etc.
