3. Daughter's Lifespan (Mean Deviation from Cohort Life Expectancy) as a Function of Paternal Lifespan Offspring data for adult lifespan (30+ years) are smoothed by 5-year running average. Extinct birth cohorts (born in 1800-1880) European aristocratic families. 6,443 cases

4. Unusual Non-linear Pattern of Lifespan Inheritance It is theoretically predicted (by quantitative genetics) and experimentally confirmed that the dependence of most offspring quantitative traits (body weight for example) on parental traits is linear. However, if some parents are damaged during early development and therefore have shorter lifespan (despite having normal germ cell DNA), the dependence for lifespan inheritance should become non-linear. This is because the offspring born to these short-lived parents with normal germ cell DNA should have normal rather than shorter lifespan

13. Paternal Age and Risk of Schizophrenia Estimated cumulative incidence and percentage of offspring estimated to have an onset of schizophrenia by age 34 years, for categories of paternal age. The numbers above the bars show the proportion of offspring who were estimated to have an onset of schizophrenia by 34 years of age. Source: Malaspina et al., Arch Gen Psychiatry.2001.
