The mechanism of evolution that has been exhibited here is known as bottleneck effect. The fact that a sudden incident of the tree falling caused the death of rare alleles and this resulted in the decrease in genetic diversity of the population. I hope that this is the answer you were looking for and it has helped you.

Explanation:
The answer is <span>C) Polymerization
Glycogen is a polysaccharide made up of glucose. It is a polymer so it is produced by polymerization of its basic units. Glycogen is the polymer (polysaccharide) produced by polymerization of glucose.</span>
