A population experiencing both immigration and emigration is referred to as what type of population?

• A. Closed Population
• B. Open Population
• C. Dynamic Population
• D. Stable Population

Answer: (B)

A population that experiences both immigration (individuals moving into the population) and emigration (individuals moving out of the population) is referred to as an open population. This concept highlights the dynamic nature of the population, as it is not isolated and can change in size and structure due to the movement of individuals. In an open population, the interactions with surrounding populations can lead to increased genetic diversity and adaptability, as new individuals can introduce different traits. In contrast, a closed population does not allow for movement in or out, resulting in more stable numbers but potentially less genetic diversity. A dynamic population could refer to changes over time due to reproductive rates and environmental factors, but the key factor defining an open population is the ability to both gain and lose individuals. A stable population would suggest that the population numbers remain constant over time, which is not the case in populations that are actively experiencing immigration and emigration.
