Regression to the mean is a statistical phenomenon that occurs when an extreme value of a phenotype in a population is followed by a less extreme value in the next generation, resulting in a tendency for the phenotype to move toward the population average. This is because extreme values are more likely to be influenced by random environmental factors that are not inherited, whereas the population average is determined by both genetic and environmental factors. Therefore, children of parents who are at the extreme ends of a normal distribution for a phenotype are likely to inherit some of the genetic factors that contribute to the phenotype, but are also likely to experience a different environment that is closer to the population average, resulting in a regression to the mean.
