The mechanism that affected the gene pool of the immigrants that entered the United states Through Ellis Island is Gene flow.

Actually it may be an important aspect of evolution; evolution can occur as a result of genes being transferred from one population to another. 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.
