No, it is not an example of a mutation.

Explanation:

Mutations occur in the chromosomes of the organism, in this case the fly. A mutation is a permanent alteration in the DNA of the fly. Therefore, if the fly were to have purple wings when it was born then it would be a mutation. However, in this case we dyed the wings of the fly purple. This does not alter or change the DNA in any way to cause a mutation.

Hope this helps!!
