Genetic inbreeding and paternal age effects. If virtues are good-genes indicators, heritable variation in virtues should reflect variation in overall mutation load. For example, the offspring of sibling or cousin marriages should show reduced virtue levels, due to the increased expression of harmful homozygous mutations (also known as inbreeding depression). Also, since mutation load in sperm increases gradually as men age, younger fathers should, all else being equal, sire more virtuous children. Such paternal age effects have been shown for various virtue-reducing mental illnesses, such as schizophrenia and autism; future research could use similar methods to investigate other virtues more directly.
