If a [[gene]] is altered in a [[germ cell]], the mutation is termed a germinal mutation. Because [[pgerm cells]] give rise to [[gametes]], some [[gametes]] will carry the [[mutation]] and it will be passed on to the next generation when the individual successfully mates. Typically germinal mutations are not expressed in the individual containing the [[mutation]]. The only instance in which it would be expressed is if it negatively (or positively) affected gamete production.
