Answer:
When directed mutagenesis which is also called reverse genetics is used, only a single mutation per genome is introduced. In contrast, the number of mutations per genome introduced by random mutagenesis is usually difficult to control. It is likely that the strain you obtained with a mutation in gene X after random mutagenesis contained an additional mutation or perhaps multiple mutations which ultimately was/were responsible for loss of virulence in your favorite pathogen.
Two diverse species naturally breed an offspring, and selective preserves raver new traits in a given environment, (they evolve).

The US Forest Service was established to sustainable management of forest resources vis a vis conservation and sustainable usage;
The US Fish and Wildlife Service was established to conserve and protect wildlife/fishes with end goal being in the benefit of the populace;

Ripples in a pond are an example of mechanical waves whereas electromagnetic waves include light and radio signals, which can travel through the vacuum of space.
