Antibiotic resistance happens naturally due to genetic mutation through random selection, however, genetic drift occurs on purpose and tests which genes are stronger and should continue to be passed on to future generations. In most cases, genetic drift is needed and antibiotic resistance isn’t.
Antibiotic resistance; occurs naturally due to a genetic mutation through a sort of selection at random Genetic drift; occurs on purpose and with tests to see which genes are stronger to see which should continue to pass in generations
