"A large population of Rhinoceroses, in a wide variety of skin colors was almost entirely wiped out by a severe drought. The few that remained are all gray, and are slowly building the population back up. What is this type of event called?"

A. Genetic drift
B. Interspecific competition
C. Intraspecific competition
D. Population bottleneck

Explanation: A population bottleneck is an event that drastically reduces the size of a population. The bottleneck may be caused by various events, such as an environmental disaster, the hunting of a species to the point of extinction, or habitat destruction that results in the deaths of organisms.

The best answer on the type of event described in the questions is ( D ) : Population bottleneck

Population bottleneck is caused by the drastic reduction in the population of a population ( made up of varying species ) due to natural events such Fire or flood. population bottleneck can also be caused by man made activities such as indiscriminate hunting of animals or organisms.
Genetic drift is the randomness in the gene variants of a population
Interspecific competition is the type of competition that occurs between animals of different species. this could be caused by the quest for territory, food or habitat
Intraspecific competition is the same as interspecific but it occurs within animals of same specie.

hence the type of event whereby the remaining gray Rhinoceroses are slowly building the population back is called Population bottleneck.
