Saving a Species


Genetic diversity is essential for the survival of a species because it increases the species gene pool. The increase in a gene pool will give the species a better chance of possessing traits that increase their chance of survival in a changing environment.

In the graph below, which of the following events took place in order for the population to recover and to increase in size?

"Population Bottleneck". Wikipedia. N.d. Web. 7 Feb. 2016. <https://en.wikipedia.org/wiki/Population_bottleneck


The population has been put into an animal reserve.


The bottleneck effect has increased genetic diversity.


The founder effect has increased genetic​ diversity.


Gene flow has increased the genetic diversity of the population.
