The mechanism that affected the gene pool of the immigrants that entered the United states Through Ellis Island is Gene flow.
Gene flow involves the movement of genes or alleles between interbreeding populations of a particular species. In other words it is the movement of genes from one population to another population.

Gene flow occurs when there is migration, since the loss or addition of people can easily change pool frequencies even without no other evolutionary mechanisms operating.
