Human genetic variation

A graphical representation of the typical human karyotype.

DNA molecule 1 differs from DNA molecule 2 at a single base-pair location (a C/T polymorphism).

Map of the migration of modern humans out of Africa, based on mitochondrial DNA. Colored rings indicate thousand years before present.

Human genetic variation is the genetic differences both within and among populations. There may be multiple variants of any given gene in the human population (genes), leading to polymorphism. Many genes are not polymorphic, meaning that only a single allele is present in the population: the gene is then said to be fixed. On average, in terms of DNA sequence all humans are 99.5% similar to any other humans.
