If the deceased left behind sons
and daughters and a tumtum (a person of indeterminate gender, with
genitals recessed and covered by flesh) – when the property is
abundant, the males push the tumtum away to the females. Since it is
unknown whether the tumtum is male or female, he cannot claim more
than the lesser of the two portions. He thus receives support until
maturity, like the daughters. When the property is meager, the females
push him away to the males, and he receives nothing, like the other
sons.
