A Mutation occurring in the population will change the allelic ratio.
<h3>What is evolution?</h3>
Evolution refers to the changes that occurs in organisms over a long period of time such that those changes results in new species better adapted to their environment and having higher specialization.
One of the factors of evolution is mutation.
According to the Hardy-Weinberg principle, the allele and genotype frequencies of a population of organism in equilibrium will remain constant in the absence of evolutionary influences.
Therefore, if a mutation occurs in the population, the allelic ratio will change.

Answer:
Dexamethasone drug in an individual lowers the level of plasma cortisol by lowering the release of Adrenocorticotropic hormone from the anterior lobe of pituitary gland.But in case of people suffering from Cushing syndrome dose of dexamethasone does not lowers the plasma cortisol level.
Explanation:
Dexamethasone is a synthetic Glucocorticoid.As a result it"s functions will be analogous to that of Glucocorticoid.Dexamethasone generally stimulate the rate of Gluconeogenesis thus increasing the production of glucose.As a result the plasma glucose level is elevated.
