If a mutation occurs, would that trait be adaptive, non adaptive or have no effect on survival and reproduction?

Adaptive

Explanation:

Not all mutations lead to evolution. Only hereditary mutations, which occur in egg or sperm cells, can be passed to future generations and potentially contribute to evolution. Some mutations occur during a person’s lifetime in only some of the body’s cells and are not hereditary, so natural selection cannot play a role.
