No, not all genetic change is adaptive.
Explanation:
This is because genetic changes happen in many ways and this can be adaptive or not.
The main form of genetic change happens through genetic mutations, and these mutations are not always adaptive.
One might think, for example, of a river polluted with a chemical reagent that causes mutations in the scale genes of the local fish population, mildly damaging the way they swim. Despite being a nonadaptive genetic change of fish, they have continued to reproduce so that this change is part of their population.
