When a nonfunctioning duplicate is fixed in the population, or a functioning gene becomes nonfunctional, the result is a genetic skeleton called a pseudogene.

Deletions are important in shaping the genome.

A recessive allele (a) that causes a genetic disease has a frequency (q) of 0.01. If the population mates randomly (F = 0), the frequency of individuals affected by the disease (aa) will be q = 0.01 = 0.0001.

However, if F = 0.25 expected frequency of the aa is .0026.

Breaking a bond always require energy to be added to the molecule. Correspondingly, making a bond always releases energy.
