Which of the following would most likely result in a bottleneck event?
A. A small population of geese migrates and joins a large flock of the same species. The two groups subsequently begin interbreeding.
B. A mutation occurs in an individual poison ivy plant, doubling the number of seeds it produces. The mutation is inherited by future generations.
C. A hurricane blows through a coastal swamp inhabited by an apple snail population. The hurricane drastically changes the hydrology of the swamp, killing 98% of the apple snails.
D. A population of broomsedge grass is studied and determined to be in Hardy-Weinberg equilibrium.
E. Two populations of lizards were separated for many years by a river. The river's course has been diverted and migration between the two lizard populations can now occur.
C. A hurricane blows through a coastal swamp inhabited by an apple snail population. The hurricane drastically changes the hydrology of the swamp, killing 98% of the apple snails.
