Chapter 27, Problem 27CONQ

Summary Introduction

To review:

The contribution of the following mechanism in the alteration of allele frequency for the emergence of antibiotic-resistant strain.

A. Random mutation

B. Genetic drift

C. Natural selection

Introduction:

Antibiotics are essentially used to prevent infection from bacteria and fungus. However, antibiotic-resistant strainsemerge, which affects the treatment of several infectious diseases. The cause of this is the increase in allele frequency that provides resistance to microorganism from antibiotics.
