Question

In a laboratory study, antibiotic resistance was shown to arise in populations of lab-grown bacteria in as few as twenty generations. As the dose of antibiotic increases, the bacterial populations continue to develop resistance to the drugs. A laboratory researcher makes a claim as to the origin of the gene that confers antibiotic resistance in the bacterial population. Which of these claims accurately supports that genetic variation could arise in the bacterial populations in the laboratory? Select ALL that apply. A)Bacteria can exchange chromosomes via homologous pairing in meiosis. B)Chromosome number can double when bacterial cells fertilize other bacteria, creating genetic diversity. C)Changes to the genome can occur when the bacteria reproduce , forming offspring with new phenotypes. D)Viable errors in replicating the bacterial chromosome can lead to genetic changes that result in new phenotypes. E)Induced mutations occur in the genome of he bacteria when the DNA is exposed to environmental factors that act as mutagens.
