The influence of the founder in population genetics is the loss of genetic advantages that occur when a new generation of the population arises from a very small number of individuals who were previously part of a larger group (for example, a small group of animals survived a mass extinction event). Ernest Meyer was the first to develop the full concept of the term in 1952, and was able to do so using other theoretical work by scientists such as Sioual Wright. As a result of the loss of genetic differentiation, the new generation may be very different from their grandparents both genetically and morphologically. The influence of the founder is believed to lead in some exceptional cases to evolutionary diversity and to the emergence of new types of more sophisticated creatures.
In the picture to the left, indigenous people have almost equal numbers of red and blue individuals, while the three smaller founding groups show that one color can become predominant or fixed (the influence of the founder) as a result of random selection from the indigenous population. A bottleneck may also cause a founding effect even if it does not represent a completely new population.
The influence of the founder is a special case of genetic drift as well as the exposure of the new population to the influence of the founder. They are also often very small populations, and because of this, they appear to be increasingly sensitive to genetic drift, increase in internal reproduction and relatively low genetic differentiation. This can be seen in the limited gene ponds of Iceland, the Isle of the Resurrection and the Pitcairn Islands. Another example of this phenomenon is the enormous proportion of the Deaf population in Martha Vineyard, which led to the development of Marathas Vineyard's sign language.
Answer: Currency varied widely from state to state.
Explanation:
Here's the complete question:
What occurred during the Free Banking Era?
a. Currency varied widely from state to state.
b. Repaying of loans was not closely monitored.
c. The Second Bank of the United States was established.
d. The dollar bill was introduced.
The Free Banking Era occured between 1837 - 1863. During this period, states issued their banknotes and it was a period that the state-chartered banks dominated.
Due to the fact that the states were privileged to issue their own banknotes, this led to variation in currency from states to states.
Answer:
Image 1: B. Insurance agent
Image 2: A. Credit checker
Image 3: B. assets and liabilities
Image 4: B. Insurance underwriter
Explanation:
Insurance agent actually helps their clients in order to make certain decisions in choosing insurance policies that suits their needs. They give them advice on insurance plans that they can go for in order to insure their lives and properties in case of emergency.
A Credit checker is one of the finance careers that actually requires the lowest level of schooling. The basic requirement is for the individual to possess a high school diploma.
Actually, most careers in finance deal with assets and liabilities. Such career people usually work in certain professional environments such as commercial banking, investment banking, insurance, financial planning, money managing and real state.
Insurance underwriters are known to be professionals who actually evaluate and analyze the risk factors that are involved in insuring people and assets.
Answer:
The correct option is;
A. Recharges freshwater aquifers
Explanation:
Sedimentary deposits or formations of rock material with sufficient porosity for water retention are known as aquifers
The episodic movement of water from land surfaces, following a storm or other unsaturated areas into a saturated zone is known as aquifer recharge
The natural source of freshwater aquifer recharge is therefore through rainfall or surface waters from wetlands.
