THREE QUARTER SISTER Meaning and
Definition
-
A "three quarter sister" is a term used to describe a relationship between two individuals who share one parent in common. Specifically, it refers to half-siblings who share a biological father but have different mothers.
The term "three quarter" comes from the understanding that these individuals are three quarters related, as they share three out of the four genetic grandparents. While they have one parent in common, their mothers are different, resulting in half-sibling status rather than full sibling status.
This unique familial relationship can often occur due to various circumstances such as divorced or remarried parents. Despite having different mothers, three quarter sisters typically share a strong genetic bond through their shared father.
The term "three quarter sister" is often utilized to clarify the specific relationship between half-siblings with this particular genetic context. It distinguishes them from other forms of half-siblings who may share a different set of genetic grandparents or have different paternal or maternal lineages. Understanding this term helps in accurately describing and recognizing the unique familial connections between individuals who are related through a shared biological father and different mothers.
