Sister

Biological sisters who share many phenotypic facial features

A sister is a woman or a girl who shares parents or a parent with another individual; a female sibling.[1] The male counterpart is a brother. Although the term typically refers to a familial relationship, it is sometimes used endearingly to refer to non-familial relationships.[2] A full sister is a first-degree relative.
