A student uses a marble simulation to illustrate genetic drift. She starts with a population of 50 individuals, represented by 25 red marbles and 25 blue marbles.
The red marbles represent an allele for longer ears in rabbits, and blue marbles
represent an allele for shorter ears. Which statement below is true?
The allelic frequency for longer ears is 0.5 (50%).
The allelic frequency for longer ears is 1.0.
The allelic frequency for shorter ears is 75 (75%).
The allelic frequency for shorter ears is 25.
