Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A small group of squirrels gets separates them from the rest of the population due to a large flood. These squirrels, now confined to this new island, begin to start a new population. This is an example of which of the following?
A
Founder effect
B
Bottleneck effect
C
Natural Selection
D
Gene Flow
Explanation: 

Detailed explanation-1: -bottleneck mutation founder effect None of. A small group of squirrels gets separated from the rest of the population due to a large flood. These squirrels, now confined to this new island, begin to start a new population.

Detailed explanation-2: -The founder effect is another extreme example of drift, one that occurs when a small group of individuals breaks off from a larger population to establish a colony.

Detailed explanation-3: -Small populations tend to lose genetic diversity more quickly than large populations due to stochastic sampling error (i.e., genetic drift). This is because some versions of a gene can be lost due to random chance, and this is more likely to occur when populations are small.

Detailed explanation-4: -temporal isolation, in biology, a type of reproductive isolation mechanism among sexual organisms in which the differences in the timing of critical reproductive events prevent members of closely related species, which could otherwise breed with one another, from mating and producing hybrid offspring.

Detailed explanation-5: -Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.
