Race - The power of an illusion :)

"Two randomly selected individuals from different populations can be closer to each other than either individual is to a random co-ethnic
For one or a few markers, in trials where an individual is compared to a randomly selected co-ethnic or a randomly selected individual from another population, in a minority of cases, the individual will be closer to the person selected from a different ethnic group, but the proportion of such cases will decrease with the use of more markers. However, if the entire genetic information is considered, then an individual will be closer to a random co-ethnic than a random individual from another ethnicity."
