Regression to the mean is a statistical phenomenon that occurs whenever you have a nonrandom sample from a population and two measures that are imperfectly correlated.
Regression to the mean occurs when the next generation regresses to the overall mean of the population.

Regression to the mean occurs when the next generation regresses to the overall mean of the population. Extreme traits trend back to the average and are not increased or decreased in terms of measure. Measurable traits or characteristics that are extreme move back toward the average value. The next generation traits move back, or regress, to the average of that trait
