The earth's plates moved over millions of years, bringing continents and other features of the earth to their present arrangemen
t. Which term explains this movement of the lithosphere? A. continental drift B. the principle of of superposition C. the theory of plate tectonics D. nuclear fusion
The correct answer is C, the theory of plate tectonics. Plate tectonics is a scientific theory that describes the movement of the seven large plates and several smaller plates of the Earth's upper layer (the Lithosphere). This theory is based on the theory of the continental drift, developed by Alfred Wegener in 1912.
Founder effect occurs when a small number of individuals move out from a larger population and then develop a new population in an isolated place such that it leads to a decreased genetic diversity in the population established by a fewer individuals.
As a result of the founder effect the genetic diversity is reduced in the descendants of the founder population which leads to an increase in the probability of having a genetic disorder.
Therefore, since the mice being blind due to a genetic defect escape from the laboratory and breeds then the subsequent generations will most likely be blind from birth as a result of founder effect.
