The fight or flight system is a reaction that the body undergoes when put in an either stressful or frightening situation. It includes both the nervous and endocrine system.
The sympathetic division of the peripheral nervous system is used in this response as the sympathetic nervous system works up the body, increases the rate of breathing, heart rate, dilates the pupils, produce more sweat and slow the digestion rate. This reaction happens in the flight or fight system.
Peacocks would not be in Hardy-Weinberg Equilibrium
Explanation:
This can be justified by the mating patterns of the female peacocks. They do not choose their mates randomly but look out specifically for bright attractive plumage in their male partners and then select them.
Hardy-Weinberg's Equilibrium of evolution mechanism was based on facts like random mating, no natural selection, mutation, absence of gene flow, and infinite population size.
They stated that organisms mate randomly with each other without any specific or a particular preference in the phenotypes of their opposite mates
