Question

The definition of mutation is "any heritable change in the genetic material." the qualifier "heritable" is necessary because: most changes in the genetic material are repaired soon after they occur. changes in the genetic material occur at random along the genome. changes in the genetic material occur without regard to the needs of the organism. most changes in the genetic material are harmful to the organism.

Answer 1

The qualifier "heritable" is necessary because most changes in the genetic material are repaired soon after they occur. A heritable change is a genetic change that is passed on to the off springs and it is not lethal. These changes can mutate and become a weakness or a strength.
