Trooper Talk: It's illegal to pass on the shoulder. Q: If a vehicle is turning left, can you pass on the right using the paved shoulder? A: There seems to be a lot of confusion regarding this among the motoring public, as we get asked this all the time. But the law states that it is NOT legal to pass using the shoulder.
Genetic variation is a term used to describe the variation in the DNA sequence in each of our genomes. Genetic variation is what makes us all unique, whether in terms of hair colour, skin colour or even the shape of our faces.1  Individuals of a species have similar characteristics but they are rarely identical, the difference between them is called variation. 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.
Variation comes from mutations in the genome, reshuffling of genes through sexual reproduction and migration between populations (gene flow). Despite the constant introduction of new variation through mutation and gene flow, most of the genome of a species is identical in all individuals of that species.
