A more thorough explanation: Ultimogeniture is a legal term referring to a system of inheritance in which the youngest child, typically the youngest son, inherits the entire estate of the deceased parent. This practice is in contrast to primogeniture, where the eldest child inherits the estate. Ultimogeniture is a less common form of inheritance and is often associated with certain cultures or historical periods.
Example: Under the laws of ultimogeniture, the youngest child inherits the entire estate.
