Most mutations have no effect on organisms. Organisms all have large amounts of genetic code, most of which has no effect. As a result, mutation of this code is rarely meaningful.
Cells know how to differentiate through a process called gene expression. It’s a specific combination of genes that are turned on and off.
<span>The mechanism that affected the gene pool of the immigrants that entered the United States through Ellis Island from 1892 to 1954 is B. gene flow. Gene flow is the transfer of genes or alleles from one population to another. The migration of millions of individuals from countries across the Atlantic Ocean to the United States is responsible for the changes in the gene pool of the immigrants.</span>
