Imagine that a random mutation results in a bacterial cell gaining the ability to grow in an environment with a salt concentration of 13%. The population this mutated cell arose from is growing in an environment with a salt concentration of 1.0%. Over the next 3 weeks the salt concentration of the environment fluctuates between 0.9% and 1.0%. What would you predict might happen to the population over these three weeks?
A) In this example the ability to grow in an increased salt concentration provided the mutated cell with a distinct advantage, therefore the mutated cell was selected for and it began to dominate over the three week period.
B) In this example the ability to grow in an increased salt concentration did not provide the mutated cell with any advantage, it was not selected for and did not dominate the population over the three week period.
