1 Genetic variation results in different forms, or alleles, of genes. 2  For example, if we look at eye colour, people with blue eyes have one allele of the gene for eye colour, whereas people with brown eyes will have a different allele of the gene. Genetic variation is a result of subtle differences in our DNA. 2  Single nucleotide polymorphisms (SNPs, pronounced âsnipsâ) are the most common type of genetic variation amongst people. 3  Each single nucleotide polymorphism represents a difference in a single DNA base, A, C, G or T, in a personâs DNA.
A monarchy is a form of government in which sovereignty is actually or nominally embodied in one or several individual(s) reigning until death or abdication.They are called the monarchs.oday, the extent of a monarch's powers varies: 1  In an absolute monarchy, the monarch rules as an autocrat, with absolute power over the state and government â for example, the right to rule by decree, promulgate laws, and impose punishments.
A monarchy is a governmental system that has one person as the permanent head of state until he or she dies or gives up his or her position. Typically, the position of monarch is hereditary, as is the case with famous monarchies like that of the United Kingdom.
