full siblings
Share both parents
Full siblings are brothers and sisters who share both biological parents, as opposed to half siblings, who share only one parent.
The term appears most often in legal, medical, and genealogical contexts where the degree of genetic relationship matters.
DNA testing confirmed they were full siblings.
In casual conversation, people typically just say "siblings" or "brothers and sisters" when full biological relationship is assumed.
