Genetic variation is an unavoidable feature of life. As a consequence of this – and unless you are an identical twin – you are genetically unique. You have a distinctive combination of genetic variants, almost all of which are shared with your parents, although shuffled into new combinations. With few exceptions, all of your characteristics, such as hair colour, height, ear wax quality, and disease susceptibility, are influenced by your genetics.
