I think, mutations are sudden changes but recombination in bacts are slower changes in DNA
but still they can produce new alleles , so mut. is not the only way.
Also, virulli infections are rare so they are not the natural means of allele-production.
But, why did you choose gametes as the targets ? ? ? They can introduce gnechanges in normal cells also... I think.
