What this article means
Full blood relationship is that existing between persons who have the same father and the same mother. Half blood relationship is that between persons who have only one of the two parents in common.
Two siblings who share both parents are full-blood relatives; two siblings who share only their father, or only their mother, are half-blood relatives. The distinction is not merely descriptive: elsewhere in the rules on legal succession, full-blood and half-blood collateral relatives are not always treated as equal in share despite standing in the same degree of relationship, which is why identifying which category applies is a necessary step before dividing an estate among siblings, nephews, or nieces.
