Answer:b. the punctuated equilibrium model of evolution.
Explanation:Fixation in biology refers to how tissues get preserved biologically so that they don't decay.
It prevents or get rid of biochemical reactions hence increasing the mechanical strength of those tissues.
Punctuated equilibrium (also called punctuated equilibria) is a theory in evolutionary biology that states that once the organisms has been fossilized or being out up there in the fossil record , it becomes table such that it will show no evolutionary changes
Answer: This is an example that can be explained by "THE PUNCTUATED EQUILIBRIUM MODEL OF EVOLUTION"
Explanation: Punctuated equilibrium model of evolution is a theory in biology that was proposed by the evolutionist which states that the population of a specie will be stable if only it appear in the fossil records. This theory explains that the changes in species occur very fast and rapid, which will last for a long period of time, before any changes can be made.
Because fixation due to random genetic drift is more rapid in blue eye person, this means that the specie of blue eye are not changing because their are fixed. A fixed gene, are those gene that always appear in an offspring and does not decay easily.
