Explain how genetic drift was not a cause of the antibiotic resistance.

Respuesta :

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.

A change in allele frequency in a population caused by a random selection of certain genes is known as genetic drift.

Antibiotic resistance occurs when bacteria change in response to the use of these medicines. So, the genetic drift was not the cause of antibiotic resistance.

What is the antibiotic resistance?

  • Antibiotic resistance develops when bacteria change itself or mutate in response to antibiotic treatment.

  • Antibiotic resistance arises naturally as a result of a random genetic mutation; nonetheless, genetic drift can lead traits to become dominant or vanish from a population, with the impacts of genetic drift being most obvious in small groups.

Therefore, genetic drift was not a cause of the antibiotic resistance.
