The answer is false,it comes from genes that you get from both your parents
<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>
The correct option is (a) 2 → 4 → 1 → 3
A change occurs in the environment. → Poorly adapted individuals have decreased survivorship. → Well-adapted individuals leave more offspring than do poorly adapted individuals. → Genetic frequencies within the population change.
<h3>
What is genetic variation in population?</h3>
- The presence of various alleles, or different gene versions, within a population indicates genetic variety.
- If there is genetic variation, then everybody in the population will have various genotypes depending on the alleles they carry.
- Genetic loci that have many alleles are said to be polymorphic. Human characteristics like blood type and eye color, for instance, are polymorphic.

The right answer for the question that is being asked and shown above is that:
The density of a certain object can be solved using two parameters: The mass and the volume.
Density = mass / volume.
So, from the given question, we are lacking on what the volume is.
Answer:
The presence of similar <u>fossils(B)</u><u> </u> and <u>rock formations(C)</u> on several different continents supports the theory of Continental Drift.
Explanation:
Alfred Wegener observed fossils of organisms that were not supposed to have survived in the climate of where they were found. Other key findings is that he found fossils of organisms that were found in one continent and the same fossils found on another continent whose edges seem to fit together.
He also observed rock formations or stratas of mountain ranges in one continent seem to fit together with another continent.
<u>Added note:</u>
Even if Alfred Wegener had these evidences to present, his theory of Continental Drift was rejected mainly because he could not explain the mechanism of how the super continent (Pangaea) split.
