half-sisters

One parent shared

Half-sisters are sisters who share one biological parent but not both—typically the same father with different mothers, or the same mother with different fathers.

The relationship is distinguished from full sisters (who share both parents) and stepsisters (who share no biological parent).

My half-sister and I have the same dad but different moms.
