when there is no gene flow between different populations
Hardy-Weinberg equilibrium
allele frequency
BottleneckThat is a condition of the Hardy-Weinberg law and the population is said to be in Hardy-Weinberg equilibrium , but it is an idealization that never happens in nature.
The immigrating individuals do not at all interact with the pre-existing population in any way.
When an organism is in Hardy-Weinberg equilibrium there is no evolution. There is no mutation, mating is random and thus no natural selection. Naturally, outside of labs this condition is never seen.
it ruins the equilibrium

Hardy-Weinberg Principle.
Mutation cannot occur
Mutation cannot occur
Allele frequency is stable

No disruptive circumstances must be present in random mating in a population for Hardy-Weinberg equilibrium to occur. Mating must happen randomly. No allele can give an advantage
A large population residing on an isolated island is more likely to reach Hardy-Weinberg equilibrium.
