Sororate occurs in certain cultures where the lineage of the deceased wife must provide a replacement to maintain the symbolic and emotional bond between the children and their mother's family.
If a wife's sisters are unavailable, another female from the same lineage may be provided. This practice, along with others like levirate and ghost marriage, highlights the cultural importance of marriage and kinship.
Levirate is a parallel practice where a widow marries a brother of her deceased husband, often observed in societies with polygynous families.
