APFIVE Chemical Mutagenesis and Genetic Variation
A population of bacteria is exposed to a chemical mutagen that causes G-C to A-T transitions. If this population continues to reproduce in the presence of this mutagen for many generations, which outcome would most directly contribute to the bacteria’s ability to survive in this environment?
A
Increased genetic variation leading to adaptive mutations
B
Decreased mutation rate through natural selection
C
Horizontal gene transfer between resistant individuals
D
Increased rate of homologous recombination
