Question
A scientist is studying two populations of bacteria.
Population A reproduces asexually by binary fission.
Population B reproduces sexually through the exchange of genetic material.
The scientist exposes both populations to an antibiotic.
After several generations, Population B shows more resistance to the antibiotic than Population A.
Which statement best explains this difference?
(5 Points)
Sexual reproduction produces genetically identical offspring, making Population B more resistant.
Asexual reproduction allows bacteria to mutate, making Population A more resistant.
Sexual reproduction creates genetic variation, increasing the chances of resistance in Population B.
Asexual reproduction results in stronger individuals, giving Population A an advantage.

The statement that best explains the difference in antibiotic resistance between the two populations is:
**Sexual reproduction creates genetic variation, increasing the chances of resistance in Population B.**
This is because the genetic diversity resulting from sexual reproduction allows for a greater potential for some individuals to have mutations that confer resistance to the antibiotic, leading to a higher likelihood that at least some members of Population B will survive and thrive despite the antibiotic exposure.
**Sexual reproduction creates genetic variation, increasing the chances of resistance in Population B.**
