Recent studies have found instances of transgenerational inheritance of epigenetic traits in humans (Relton et al., 2012). Females
already possess their eggs at birth, whereas males do not produce sperm until puberty. For epigenetic modifications to be
inherited by the next generation, the modifications must occur in the germ line of the parents. The data in the table was collected
by a study conducted over decades with over 14,000 families. The study was used to analyze the impact of parents' behavior on
their children, including behaviors that occurred long before reproduction (Pembrey et al., 2006).

shown in the data table.
