Explain how this experiment showed that gene flow was not the cause of antibiotic resistance.
Alenkinab [10]

Answer:

Due to no transfer of resistance allele.

Explanation:

The gene flow was not the cause of antibiotic resistance because the characteristics can't be transferred from one generation to the next generation. The organisms are evolved to become an antibiotic resistance due to their environmental conditions and this resistance quality is only present in the existing population and the alleles that are responsible for this resistance can't be transferred from the bacteria to the next generation so the experiment showed that gene flow was not the cause of antibiotic resistance

ICE Princess25 [194]

Answer:

Reduce genetic diversity

Explanation:

Genetic diversity is an extremely important factor when it comes to evolution. The more diversity and variation there is within a population, the more chances a species has of surviving.

In the case of inbreeding, organisms that are related are selected to mate. This has extremely negative effects on the species such as bad health and infertility issues. In addition, because they all share the same alleles, it results in a decrease in genetic diversity, augmenting the chances of the species to disappear.

This occurs because if, for example, there is an organism that possesses a capability to resist extreme weather conditions and another that does not have this trait, there are still chances to survive, whereas if they are all the same and none of them possess this capability, the probability of this species to go extinct is higher.
