Answer:
Genetic drift
Explanation:
Genetic drift is an evolutionary mechanism that in a population it changes allelic frequencies over generations just by chance. For this reason, small populations are more susceptible to be affected by genetic drift than bigger populations.
In this example, Indiana Jones visited a small village of 50 people and over generations allele A probably was lost just by chance, or by genetic drift.
It can potentially wipe out the population of a certain colour of butterfly.
