Answer:
Limited resources for the population
Answer:
Population 3
As there are more number of individuals in this population , allele frequency is least likely to alter because of accident which may involve not many butterflies.
Population 1
Bottle neck effect causes more losses due to genetic drifts on small populations. So population 1 with 50 butterflies is most susceptible.
Population 3
Population 3 has the highest frequency of the brown allele.
Population 1 = 5/45 = 0.11
Population 2 = 125/500 = 0.2500
Population 3 = 313/1250 = 0.2504
